I still have my trusty pay-as-you-go Nokia 3210 (I got it off my brother 3rd-hand 3 years ago). Well, trusty until recently when I've been dropping it a bit too often, such that it randomly turns itself on and off, the display smudges occasionally, some keys don't work properly, and something rattles inside (i.e. its damn well not supposed to). Personally, I'm interested to see how long I can keep it going for.
Myt332 - I feel your pain! The reason I have this one now is that 3 years ago some bastards mugged me (and my old Motorola T180) on the tube in London (and it was barely past 23.00 hrs)! Oh, and they got some money off of me as well, though at least my bank later refunded me, along with a letter from the police saying they'd arrested the wankers (caught on cctv that was apparently working)!
Still not worth the trouble of replacing all those numbers though!
