i need a new phone, and i'm planning on buying Nokia, cos they have been most reliable out of all the phone's i've had. i'm looking at either the 7650, the 3650 or the 7250 ? i'm not really bothered about size, as long as it aint ludicrous, and the 7650 n 3650 are free on the contracts i'm lookin at, whilst the 7250 will cost me £29.99. please help! cheers mush.
