I've owned, and destroyed, loads of phones in this list, even ones I'd forgotten about.
Nokia 5110 - everyone had one of those. Stupidly I sold mine for a Ericsson A1018 which was rubbish.
The Ericsson R380 was a great phone but took over an hour to free the message memory (about 100 texts). I dropped it in a Tesco car park and the buttons all fell out, it was never the same after that.
Nokia 7650 was a phone ahead of its time but I bought one with a faulty earpiece on eBay and tore the ribbon connector trying to replace it.
Orange SPV - buggy as hell and mine packed up in short order. Shame as it had potential.
Nokia 6310i I had for 5 years (longest yet) - the power button fell out die to being dropped too often and soon after I was given a E65 which got nicked soon after.
Current phone is a Nokia C1-01 - good hardware and software. I bought a N95 on eBay a few months ago only for the display connector to pack up, so the C1 it is for the foreseeable future.
