hehe , DIE Pathik.
Get the K850 coz its in your budget. The n82 may be a good phone, but has a crap keypad and if you are an ardent sms er you will find it very hard to cope with. I have the K850, as like many guys in this forum, and am loving it. Great sound qaulity and great cam. If you dont have need for symbian applications, i suggest go for the K850. The C902 is 19k, go for it if you can afford it. the latst firmware, as i have seen in esato takes better pics than the n82. Go check kor urslef. Theres a comparison in the C902 pics thread.
