I bought nokia 6630 some 5 years back.and still using it.though I am not a mobile freak but yes its a phone which is providing me the services I require.
When I purchased it, it was a new entry in 3g phones.and recently I came to know it is one of the phones which can be used internationally anywhere. Isnt it great!!
Its a very reliable phone and is working fine since I purchased it.battery life is good 2-3 days in standby mode. Now the battery is a little weak now but still the phone is working phone.
The features with which it comes are
(1) 3g phone
(2) 1.3 MP camera
(3) bluetooth
(4)GPRS/WAP
what I miss is a USB port but that was not available in any phones that time
the other thing is the size.its a little bulky.
overall I am happy with the phone
and after seeing its reliability I will go for NOKIA again.(once bitten by samsung)
