Iphone has finally arrived.

Iphone has finally arrived.


OMG, apple has atlast made an iphone that even a nokia N97 uberphone geek cannot ignore. what more? while nokia phones are more like technology previewes, iphone really works afaik.
I just heard roumers about apples intention to announce iphone 3g S this week and before I could wink it was announced.

Damn, this is the nokia killer i-phone. Trust me, if only apple got the pricing right in markets like india, its sure to kill the highend nokia phone(N/E series a' la n97) market here. Apple seems to have got it almost right this time and more importantly it sure has the hardware to do it, even if some minor feature additions could be done in an update.

I was shocked to see the feature list of the new iphone 3g-s . I just started browsing the apple iphone3g page and it seem to be goin on and on. even the nokia tech spec page woulnt have lasted so long. and each feature after feature seems to be a direct answer to nokia's N97 (or other similar clones). the camera seems to be almost close to the 5MP(or 8mp) in the N series at 3 MP, with video recording at near DVD quality VGA @ 30fps), auto focus, it has almost managed to equal Nseries camera features. but for a casual pics/phone cam its good enuff. I just miss the videocall camera and since the hardware is missing, it might not be upgraded later too.

I heard the iphone might also have a FM transmitter and receiver. wow. that would save from buying a external transmitter.

While apple has caught up nokia in the uberphone space, nokia seems to be sleeping with its still outdated processor speeds, buggy software and most features practically useless.

I will write more on this later doing a full comparison of the N97 and the iphone 3G S and based on it I might buy one of them and hoping apple releases them in india soon in retail and not at those dizzy 45k heights but hopefully around 25k if not at $99 as in the US.

The Iphone killer is here

Nokia 5800xpressmusic

Is this the real iPhone killer? I guess so atleast in India. its not a geek phone but has all the power and features including the ubiquitous touchscreen interface, the first from nokia on S60(V5)( barring the previous attempts on the S90 platform). Infact I would go ahead and say this phone is better than even the legendary N95. N96 still have a couple features and more storage but nevertheless for the price of about 20k in India, this phone is a sure killer.

Just look at the feature set in the link above....just feels bad its not in the Nseries though it has the same features or even more. May be Nokia wanted to place it in the league of lifestyle,music phones than the geek gadget series i.e., Nseries.

With the huge High definition (16:9 ratio) 3.2" touch screen (compared to iPhone's 3.5") and dynamic touch interface, accelerometer(automatic orientation, movement based control...), tactile feedback etc, 640x320 resolution (compared to 480x320 in iphone) it's close/betterthan to the iPhone experience though multitouch is missing.

with 81MB internal storage(for phonebook and base storage), 8GB default storage with an addon microSD slot you can swap memory and also grow it to 16GB now to 32GB soon. this is surely where the 5800 beats the iphone which has fixed storage with no addon memory.

What more, it has the same quality camera with carl zeiss lens, LED flash and video recording at near dvd quality(,geo tagging with gps?), which was the cornerstone of the N95 series. at 3.2MP its good enough for most digital camera needs. I used to reduce the resolution to 3.5MP even in my 5MP N95. A xenon flash would have been better and may be a CCD sensor instead of cmos for true digital camera experience but yea I am asking for too much compared to the iPhones barebones 2mp camera without even autofocus or video recording. It also has a front camera for 3G video phone calls. A camera lens cover a'la n95 would have been good.

other features include the A-GPS with voice navigation(I heard its free), which is better than N95, a best in class music player with 1 year free subscription to nokia's music store, which makes it truely compete with the iphone's iPod feature.

yea the DVB-H feature of n96 is missing but who provides such a service in india? its at the best a techno preview.

sure it has a FM player as other nokia phones and a basic feature thesedays which ofcourse is lacking in iPhone.

new features of S60v5 include a better UI, easy access menus without the clutter of older S60, dedicated quick access buttons for keyfeatures like music player, bluetooth etc...
Surely nokia is listening to its users and also learning from competetion.

want more, here are the standard S60 features now,
push email for exchange,
a safari based good browser with flash video support,
quad band world phone,
3.5G wcdma hsdpa,
MMS(iPhone lacks this basic feature),
bluetooth with a2dp/AVRCP stereo headphone support,
voice recognition, tts engine etc
Push to talk,
j2me java support,
TV out,
standard headphone socket,
remote control mic,
wifi 802.11b/g
Ngage platform with motion sensor controls for great gaming experience.
built in office application viewers,
Flight/PDA mode.
integrated VOIP/VPN client - to be checked...

last but not least it is a nokia S60V5 phone which can run all the millions of 3rd party S60 applications and all the other advantages and features of S60 as I had blogged earlier

but for the downside, it as most nokia phones doesnot have the muscle power to handle the load. with a 370 Mhz arm 11 processor it will sure be much slower and less responsive, especially when loaded, compare to the powerful 650Mhz arm11 of iPhone for relatively less apps and load.
The RAM seems to be ok at 128MBwhich is good enough for multitasking and load 10 or more apps. This was a major issue in the N95classic with just 64MB RAM but was corrected in the 8GB and US versions of the phone.
Also I will need to check the battery life but with its BL-5J 1320 mAh battery I guess it should be decent.

looks like things are getting closer to my dream handheld

Looks like iPhone has made it big atlast with iPhone2

This is a follow up to my previous post on N95 and iPhone. Sure N95 was way ahead of its time and till today the N95(8gb) and N96 stands up to its legendary reputation of being the most geeky and loaded phone. but Nokia has not caught up with its competition in certain technologies like touch screen, though they brought out higher storage. Multi touch UI is an essential technology today and this is going to make nokia loose if not kill them.

Yes I criticized and cribbed about many basic features lacking in iPhone 1.0. looks like apple as usual listens to its users and as always makes what ever they provide work best and practical(unlike nokia which is more of techno demo and practically not so well usable). Now check out the new iPhone 2.0 seems very promising.

Now we have GPS(voice guided navigation?), 3G HSDPA and open application support(though not opensource yet which probably apple will never make). The major short comings of iPhone 1.0 has already been solved. With 3rd party apps(ala nokia S60) any new feature can be added. Also apple is updating the OS for its older iphone 1.0 hardware which is a good sign of continued support(which nokia lacks as they kill a model after a years support and their very expensive phone becomes outdated and useless in less than a couple years).

Moreover day by day iphone seems to be beating S60 handsdown in quantity/quality of applications and user community support and is becoming a defacto platform for any application developer, which along with the brand reputation of apple and style statement even with the non-geeks and fashionistas would be a more accepted and supported phone universally(as is the ipod inspite of being proprietary). This along with its main USPs like the multi touch UI, large(perfect) screen size for a handheld, a very usable desktop class browser(plugins someone?), better build quality, finish and choice of materials, iPod, large storage etc Nokia will have to do a lot of quality improvement and standardization to get anywhere near the iphone now that iphone has caught up with Nseries already. Sure iPhone is becoming the iMac of the handheld world.

I am yet to see the complete feature list and if they have fixed basic issues like MMS, setting ringtones and front cam support for video conf, replaceable battery, replaceable sim, higher res auto focus camera with flash, TV out, DVD quality video recording, PTT, VOIP(avl thru 3rd party already), j2me, radio etc. , some of these features are s/w only and can be added by 3rd party apps or an upgrade. the hardware sure is promising and much more faster than any Nokia phone today. I will give a complete review when the phone is out in India(damn, they still lock you on to a operator which is a new concept in India which was always used to unlocked mobiles thanks to Nokia's business model).

Anyway as of now all I can say is the iPhone 2.0 looks very promising and I will most probably get one when its launched here as long as there is no real iphone killer from Nokia.


Well, Airtel has at last launched iPhone in India. but at Rs.36100 for the 16GB version I don't think its worth the price, given that it will also be locked to Airtel network.
more details here,

iphone 3g at best can be purchased if offered at the $200 price that apple has quoted for the older iPhone. in India it is worth purchasing at a price of 15k to max 20k. Given that it is a proprietary product and most apps for it is very expensive and its not easy to crack stuff or get freeware, this is just a fancy toy for the rich who want to flaunt a fashion accessory and not for the geek who wants a power gadget.

The nokia N96 is a good bet instead. Damned nokia as always does leave more to be desired. at the minimum a touch screen should have been provided, which is a basic feature of contemporary high end handhelds/phones. but yea for those who already own a N95 it doesnt offer much more than 16Gb storage and dvb-h live tv receiver +build in accelerometer apps.

Driving skills training

This blog was sent to me by one Dr.Adhiraj Joglekar who commented on my blogs on bangalore traffic and I found it very useful and thought this should reach every Indian.


watch the videos and forward this to anyone and every one you know in India irrespective of they drive/ride or not. Ofcourse don't just watch videos try to follow them while you drive, than just crib about the mayhem we see on our roads or curse the others. most drivers in India are not even aware of the fact that there are road rules and what that white/yellow lines that you occasionally see on some roads are meant for.

These videos teach some small things which we overlook while driving but this can have major impacts on quality of driving and saftey on our roads , but most importantly is an attempt to change the image of India around the world as an object of ridicule when it comes to traffic management and civil/road sense. I am starting a email forward campaign in the hope it will educate some of the so called educated who use the net and then have a snowball effect. Hope.

last but not least do drop a line of appreciation for this man who made these videos.

The chakravyuh at KR puram - the traffic mayhem that I go thru every day.

The Chakravyuh

Note:- this video was not taken during the peak hour jams(8 am to 10:30 am and 5:00pm to 8:30 pm) but taken during non peak hour at 1:00 p.m. when the route was relatively free. Even at this time this one KM stretch took 10 minutes to cross. Two other bottlenecks which follow immediately after this railway underpass pass at the flyover crossing and another under the cable bridge were relatively free at this time (which other wise is choked during peak hours) and also Whitefield road which gets vehicles piled up for 2 kms from the bridge was free at this time. Otherwise it would take more than 1 hour to travel from Narayanpura bus stand in Whitefield road (one KM from KR puram bridge) to Big bazar on old madras road or the reverse way. A distance of 3 kms.

the following steps can make traffic flow freely and make this area into a region of world class infrastructure.
1. By just expanding the Beniganahalli railway underpass to 8 lanes width (Ironically the bridge just a few hundred meters away at NGEF-kasturi nagar road is 8 lanes wide while the road under it is just two lanes, whats the problem with railway engineers? did they reverse the contracts by mistake?)

2. add one more lane after the Eeniganahalli railway bridge between the left turn to flyover connecting ORR and end ramp of the flyover from rammurthy nagar ORR. it is just two lanes now. there is enough space to make way for 3 lanes by taking space from the unmaintained park under the ramp.

3. fix the medians and road islands. the fence from these are protruding making vehicles avoid the lane close to these.

4. reduce the length of the ramp to the cable stayed bridge by a few hundred meteres. you dont need a 700M ramp to this bridge which is just 6-8 M high. Remove the busstop at the beginning of the bridge. provide a pedestrian underpass as the road width becomes 12 lanes here. mark bus bays and make sure bus stops only in these. the bus bay present after the HP petrol bunk is not used now and busses park in the middle of the road which is a crossing area for vehicles from below and above the bridge.

5. remove the lorry repair garages, encroachments and indiscriminate parking of trucks on the left lanes of the stretch.

6. remove the encroachment by KR puram railway platform of 2 lanes of road under the cable stayed bridge on this stretch. this is really the peak of it. a railway station encroaching on a national highway and creating an acute bottle neck.

7. expand the road to atleast 8 lanes on the stretch between the underpass of the cable stayed bridge and whitefield road/ORR junction. This stretch is now just 4 lanes which cannot accomodate traffic from the 4 lane whitefield road and the 6 lane ORR and its 2 service lanes.

8. on the stretch from the cable stayed bridge underpass(KRpuram station enterance) to the HP petrol bunk near Pai layout the road suddenly becomes 2 lanes from 4 lanes due to an encroachment by a shop and the entrance to a mosque. I guess this can be corrected and made into proper 4 lanes even without disturbing the mosque building.
if possible provide a service road to Pai layout and make sure vehicles coming in and out of this layout do not criss/cross the traffic on the main road.

9. last but not least lay pothole free quality(atleast as good as toll national highway) roads and mark lanes clearly. mark main lanes, service lanes, bus lanes, cross over areas and lanes leading to the various flyovers etc. this is really important.

just these nine steps is enough to make this stretch a world class infrastructure with smooth flow of traffic. Of these steps expanding the railway underpass and clearing the 4 other bottlenecks (ala ramp length, railway platform encroachment, 8 lane between KR puram station and whitefieldroad/orr junction, and mosque encroachment) alone can make this stretch traffic jam free.

Applications for N95 and S60v3 multimedia devices - review

Here I will review and post information on some interesting and useful free/commercial applications that can really enhance the productivity of your N95/Nseries or other symbian series 60v3 phone.
Do watch this space as I will keep adding new software information as I find time.

Security Genius

This is one must have software that could help you possily trace your phone if someone stole your phone or you lost it.
This program is started automatically(and thats the only way to start) when you boot the phone and runs in the background.

the only way to access it is by dialing the access code *#123456# (which can be changed). once you get to the screen you can ser the password, 2 phone numbers to which this program will send SMS to in case someone changes the SIM card without your knowledge. you can also customize the message that will be sent to the numbers.
Since this is a security software it resides in stealth mode, i.e., not listed in the menu or installed applications list and cannot be uninstalled.

Download the trial version from one of the popular shareware sites for series 60 like symbianware.com , allaboutsymbian.com , my-symbian.com , handango.com etc . official site is http://www.symbianon.com/
tip:- the trial version can be reinstalled any number of times after expiry.

DivXplayer for series 60
Looking to play your dvds from your mobile, here is the right software for it. DivX's official player is free to download. All you need to do is register at stage6.divx.com and download it.
more details here http://labs.divx.com/node/250

Now rip your dvds in divx without loosing quality transfer them to your mobile and watch them on the move.
smart movie is another popular software for the same purpose but its not free. though cracked versions are common, why use them where there is a free option. DixX player also brings in generic avi file support.

Nokia N95 review

Bangalore Traffic Photo blog

Here are some photos I took when travelling in bangalore to/from office or other travel to reach my destination and was stopped and diverted or caught in a traffic jam for absurd reasons like someone suddenly built a tent in the middle of the road or buffaloes were happily grazing in the median in an arterial road during peak hours or a conservancy worker was stopping the choke-a-bloc traffic just for cleaning the road at 6 pm.

Big daddy just took over the road. sorry the way belongs to him now.

this ancient piece of metal which still has an engine and called as a lorry in india just blocked the 20 ft road at is the only exit road to my block of city. now I dont have a way to get out of my road. question them, oops you might get beaten up. call the cops? they dont care and wont come unless you pay them the cost of the lorry.

This was a picture I took before the 16 floor Mantri Altis, the most posh and expensive apartment in downtown bangalore, in cunningham cross on cubbon road opposite chinnaswamy cricket stadium. yes downtown bangalore still has medows where buffalo herds still graze during peak hour traffic.

hai hai! tch tch! wondering what that is? the greatest indigenous vehicle invented in India. the bullock cart. still rules the roads of bangalore. and this one was blocking the lead road to my block and all I can do is go behind this at 2 Kmph with my 105 BHP car. Overtaking ? not possible.the road is just 20 ft in which 10ft is encroached.
I wonder why they sell cars in india.

What do you think that is? a lane or gali? nope. thats the main road to a full 4-5 blocks layouts behind manipal hospital on airport road. this 20 feet road which narrows down to 10 feet after the gate is the only way to access these layouts where it is not possible for 2 big cars to pass parallelly. this is not an exception but a norm in bangalore. most mainroads in private layouts are just 20 feet and that too partly encroached.

oh! thats not someones backward. thats the 9th main (LOL here main roads are just 20 ft wide) road new tippasandara. one family here decided to take over the road for a couple days for a family function. what do road users do? well go back, they dont care if u go to work or not but they need the road today for their family. the shamiana (tent) was just being built when I took this pic. for the next 2 days they had a complete shamiana with walls on all sides. question them? well! du want to get beaten upby a family and all their relatives? call the cops? oh I tried. looks like they were already tipped ;)

Supply chain! a coke supply van parked in a no parking zone at 9:30 a.m, blocking traffic. this is the scene every day during peak hours on this road and many. you can also see garbage collection trucks and other supply chain vehicles blocking traffic in almost every road in bangalore. Conservancy work, garbage collection, supply chain etc always hapen only between 9am and 11 am here blocking traffic. I guess 6 am is midnight for the bangalore corporation. or may be they just love traffic jams.

Attraction? Distraction in traffic? relaxation in a jam? ;)

a panaromic view of Malleshpalya! one of upcoming layouts inside kaggadasapura. 100s of 5+storied apartments of all shapes and sizes. 10s of 1000s of houses all locked inside this area called mallesh palya inside this maze locked on all sides without exit roads. the only entry/exit point into this maze of apartments is a 3KM long 15 feet road which connects to the 30ft BEML to kaggadasapura dead end main road somewhere near the middle. houses houses every where but no roads to reach them. soon helicopters and flying machines will be the only means of transport in Bangalore.

Haphazard growth, condo clusters, skyscrapers, ghettos, slums, villages, manufacturing industries, software parks all mixed up without a proper plan and zoning. more views below.

ahh! thats just the way construction steel is carried. this is pretty safe. i'll add more pics of steel rods protruding 2 meters out of the truck and probably poking some bikers in their face or breaking a windshield. this is the de facto supplychain standards in india.

more vehicles with extra fittings as promised.

The reason why Bangalore is a clean city. thats the conservancy workers dumbing garbage collected from near by areas into a truck at 10 am in the morning blocking the narrowest point in Nagavarpalya main road and helping traffic pile up on either side for few hundreds meters and giving office goers some stress to start with before the enter the mayhem on the arterial roads.

no its not some rural village where I took this pic. this in in the heart of indranagar bangalore. Tractors are the standard way of transporting water, household items, gas cylinders etc. its the pickup truck in bangalore and also help in creating designer pot holes on muddy roads using its tyres and occationally topple over to block traffic for half a day. this along with stray cows/dogs, bullock carts and mud roads help feel the aura of a rural village right in the heart of bangalore. you never know, we might soon find paddy grown in the medians.

Drivers delight ends with a nightmarish surprize. The NICE peripheral ring road around bangalore. this is the section connecting mysore road to bannergetta road. the road is amazing, best by any global standards 4 lanes + 2 service lanes with walls on both sides and a 2 lane lawned median and shoulder and central drains. 200KMPH will be a breeze here if you have the horsepower but surprize surprise. the politicians in bangalore dint want this to happen. so they made sure a farmer who wont sell his land which is needed to complete the last 200 mts to connect bannergetta road built a wall just to stop the road abruptly and even the mud paths to the side of it to reach bannergetta road are badly dug up so if you wanna try some adventure sports and smart enough to maneuver your car thru a 5 feet wide ridge without toppling it you can proceed to bannergetta road.

Traffic jam on a 6 lane(+service lanes) expressway for miles together. This was when I travelled from bangalore to chennai on NH4 expressway. Apparently the highly intelligent and scientific traffic police of Bangalore had setup Nakabandis (baricades which block the roads completely and would let just one vehicle pass it after turning the steering to extreme right once and extreme left once) before and after every junction and dint care to remove them during peak traffic. this helped traffic pile up for 15 kms continuously on NH4 from electronics city to hosur border. it took me more than 2 hours to travel 20 kms on a 6 lane _expressway_.

Apparently Bangalore police had learnt some dangerous life threatening brute force techniques to control the unruly traffic from the Tamilnadu police like nakabandhi to check speed/alertness of driver, road bumbs called speed breakers which break the bottom of your car or can trip a two wheeler rider caught unawares and kill them and so on. Unfortunately they over did these in numbers (thinking with the one grey cell left in their brains) like have a road bump every 100m and a nakabandi every km that too at peak hours. Also they ignored to learn the other skills needed to make these tools effective from the TN police like employing brute force, rowdy nature, hard work(like working 16 hrs a day), some pragmatic sense and most importantly to report to duty , patrol at night, be around to put the tools to use and remove the tools when it makes the situation gets worse.
