The question on the mind of Almost everyone looking for a new cellphone...Nokia 6600/6230 or Sonyericsson K700? For starters...the prices of the above phones Sonyericsson K700- Rs.17000( dual front type, innovative design, good build quality) Nokia 6600- Rs.17500 (Oval in shape, pathetic plastic built) Nokia 6230- Rs.18000 (Traditional Nokia Design, decent build, plastic..but shiny) All three phones are tri-band...i.e. GSM 900/1800/1900... All three cellphone's are amazing phone (i had a chance to play with all of them...YAY!!!), I liked the Sonyericsson K700 the best...but you decide after this... Dimensions and Weight Sonyericsson K700- 99 х 46 х 19 mm, 93 g Nokia 6600- 109 x 58 x 24 mm ,122g(Bulky for ya'll tight jeans people) Nokia 6230- 103 x 44 x 20 mm,97 g Display: All of them have a 65k colour display,K700's being the brightest, but kinda fades out in the sun,The nokia's colour display is more visible in sunlight. Screen Size Sonyericsson K700- 176 х 220 pixels, 7 lines Nokia 6600- 176 x 208 pixels Nokia 6230- 128 x 128 pixels, 5 lines Ringtones-Polyphonic in each phone, K700 having 40-chord polyphony and the nokia's having 16-chord polyphonic tones, but mp3's can be set as ringtones using applications that can be downloaded from the internet. Connectivity: All the phones have Bluetooth,Infra-red & GPRS Memory:Sonyericsson K700- 41 mB shared, 32mb usable Nokia 6600- 6mb shared + mmc card support Nokia 6230- 6mb shared + mmc card support Entertainment: the k700 supports java MIDP 2.0 as well as 3D java games..which are AWESOME!!, it also supports MPEG4 videos as well as .3gp videos the nokia's support java midp 2.0,but no support for 3d java...being symbian phones..they do support symbian games and applications.both the phones support .3gp format videos. Camera: Sonyericsson K700- awesome VGA(640 * 480 pixels) camera with flash, video recording, only restricted by memory, so about 30 mins of video can be recorded. Nokia 6600- VGA camera,max 9 sec video recording on one go, can be increased by installing java/symbian appz Nokia 6230- VGA camera ,max 20 sec video recording on one go,can be increased by installing appz. EXTRA EXTRA: 6230 and K700 have FM radio,surprisingly FM is missing in 6600, T9 text input etc. Functionality: Sonyericsson K700- well...almost the same software as the t610 in functionality...but much more faster and no hangups even if the phone is used till the maximum limit.Games run smooth, sound quality is damn good and themes...are amazing.Easily transfer all your files to ure K700 via an infra-red port or Bluetooth adapter.The camera is VERY clear and the display VERY sharp.comes pre-loaded with 4 games, 2 of them being 3D, download as many as the memory can take. Nokia 6600- Same software as the nokia 3650,only slower and less reliable .The phone hangs up very easily and cannot take too much pressure in terms of using software, applications often stop working and in order to make them work again, the battery needs to be taken out, so if you overuse your phone..be ready to switch it off atleast 2wice a day. Nokia 6230- Decent ...better than 6600, much more reliable, the phone dosent hang, everything runs smooth, but does slow up a little at times,but much better than all the earlier nokia symbian phones. Conclusion: I found that the K700 was the fastest and the most reliable phone out of the lot, but if you plan on using the phone as a digi cam and a music player, make sure that you 1st convert the files into .amr/.wav format first in order to reduce the file size.Exept for the mmc support, the sonyericsson K700 ROCKS.But if u want really good quality mp3 songs on ure phone and want a symbian os phone, then go for the nokia 6230, never mind the small screen and the traditional nokia design, because the 6600 is wayy to bulky and slow for all this.Well this is just what i think..the rest is upto you...ROCK ON!!!
