There are only 2 major differences between the two. The first is the obvious difference in visual appearance (the t630 has a keypad similar to the k700i) and the second is the camera. The camera is slightly better on the t630, supporting photos of up to 640x480. All in all nothing to warrent upgrading a t610 to a t630 - but if you are buying new, rather get the t630.

Stop talking cr*p rich_17! We all know that there are major pit falls in the t630s design and software...I mean come on! Rather get a nokia! At least u know wat u getting

Dont buy t630,only cif cam (remember,just xtended to 640*480,so no detail like vga).sw not smart,i think b8r cx65 for ur money

remember the dam fone is ancient

Sony phones are fantastic I've had nokia's had prob so always came back to sony i have got the k300i brill phone for the money it cost

Had my t610 about 15 months i love it has served me well only downside is now my joystick plays up due to wear and tear .. I will use it til it dies but maybe wont buy another phone of any make with a joystick

My Girlfriend recently gave me her T610 and i'm happy with it. She's got the T630 and a Motorola Razer V3 and yep she's had probs with the T630.

Im stil usin my t610, its da best thing since sliced bread!
