Does anyone have recommendations for buying an used iPhone? On AT&T family plan that we're trying to quit (up in April 2014) but still want to upgrade my old 3GS, which will be unlockable soon. Anyone tried buying these from eBay, Craigslist, Gamestop, etc.? What is the experience like? Or is it just better to get an iPad until my contract is up? (Mainly want to play games.)
Use Glyde.com. That's how I sold my old iPod Touch, it was super-simple and fast, I'm sure the buying process is the same way. It also guarantees that you won't get ripped off with a fake deal.
