there are a lot of phones in this range...tht shud serve your needs..W200,W300, Z550i, Nokia 5300, Nokia 6131..if u go a bit higher around 9-10k then there is the SE W700i, Nokia 6233 and 6300...
Neways if u wanna stick to this budget then i think w200i is a good phone to buy...as it more than matches your requirements..but mind you, it comes with the m2 memory card which is a costly thing to buy shud you need more space..prolly u'll have to be happy with the 128 mb card supplied with this phone...
The Z550i comes at a similar price but it is a better overall phone with a 1.3 mp cam, a better 256k 176x220 display than the w200i's 65k 128x160 res unit..only problem in getting the z550i is tht u'll have to buy the datacable and mem card separately..cos the mem card supplied with it is only 64 mb, i think.. the w200i will probably come with the datacable...
