I'm sure a lot of people still have some old phones lying around, i simply keep them just so i can say "oh i got one of those!" and because i have had phones since 2000 so i've had a lot and i still got some of the ones i used to use. But anyway heres the old ones i still have...

Sony CMD-J5
Nokia 1100
Nokia 3510i (No Batt)
Nokia 5510 (that's that blue one based on the 3310 but with QWERTY and music player)
Nokia 6310i
Nokia 5140
Nokia 6800 (the one that folds open to reveal a QWERTY keypad and that Bounce game is a true mobile gaming classic!)
Nokia 6230i
Nokia 7650 (the first Symbian OS v6.1 phone, first Nokia with a camera and the first S60 phone!)
Nokia 3650
Nokia 5110 (my very first Nokia, snake is legend and will always be legend!!)
Nokia N-Gage
Samsung SGH-A800

All are fully working apart from the 6230i which is completely dead even with a confirmed working battery!

I find ones like the 3650, 7650, N-Gage, 5510 and 6800 are quite hard to find now.

None but I do buy 2nd hand phones on their own or in job lots but I tend to recycle them at tesco for reward points or sell them on.

I have a Nokia 3110

Sony Ericsson T39, still works beautifully. I love that phone and still use it when I am going out drinking on a night, instead of taking my iPhone
