I want to get a new mobile phone that will take a bit of punishment and still function. I had an old Nokia and it got some abuse but still worked for 4+ years. Then it died and I got a Nokia E51 and I've already cracked the screen with LED going all over it. I need a phone that can get dropped, drooled on, eaten etc etc and still survive.
Pretty sure there is a new Nokia 3720 that is 'durable'. I'm not sure if it'll last like a 5140 which i'd bet is the one you had but it should be at least better than the normal run of the mill ones.
