Thank you for your time for replying me

one more request, can you please mention the source of the information

I would b really glad
Just to be honest, I already own a PMP (ZUNE) so multimedia is not some thing i press in a mobile, my main needs are really good data support, good battery life for long talks

and if possible a camera
even most of the time my mobile is on vibration mode
My colleague's dad is using this phone. We selected this phone due to it's high speed navigation, superb battery backup and a decent camera.
We did lot of testing on the phone. My friend was using this phone for past 8 months. Even now, it's very fast.
anyways, from gsmarena:
Final words…
Nokia 6233 impressed us from the very beginning. During the tests we were convinced that it is user-configurable in almost every possible way. The menu is organized logically; functions are detailed, offering high control comfort and brilliant work efficiency. When compared to other Series 40 phones, this one has taken care of a lot of their drawbacks. We can say for sure that it’s a trustworthy successor of the famous 6230 and 6230i business phones.
The phone has a very nice design, although a bit on the conservative side, we must admit. It doesn’t have the looks of a very expensive device and on the other hand it’s not expected to be one. There is always a possibility to go for the cheaper

While being cheaper in price, we must say that it also has cheaper looks – but that’s our personal taste of course.
Summing it up, the feature-rich package would undoubtedly turn this handset into a market hit. Just wait and see.
The champagne color looks more pricey than black/white/blue. Actual Price is same for all
6233 is good choice for its features and also for its sober looks
you can also go for 6300 that looks better than this one but both in features and battery life
with much less than 6000 you can get e250, slider phone that looks really nice
you can consider k750i or k550i or k530i also
Hell no for 6300. I had to throw my phone away as I had to charge it atleast twice everyday. very bad signal reception, very bad speaker quality, pathetic camera. This model is worst mobile ever made by nokia.
