My current is a 32GB 3GS (yes, skipped the 4's - wife has a 4S), so I'll be giving the 3GS to the kids to play with (mostly the 4 year old) so they'll leave my wife's 4S alone!
Mine's an original iphone so I doubt I will get any money for it on ebay.
Since the new one is coming and most people got the iphone5 and a lot more are getting them, what are guys going to do with your old iPhones?
Keep it?
Gift it?
Put it in the drawer?
Sell it?
