I am looking to buy a used iphone and have been looking around on ebay and craigslist and yes some are obviously scams. My question is, what should I look out for and what questions do I need to ask first off. I have been asking what firmware its on and if ever jailbroken, is it up and running right now, stuff like that. A few people told me it was stuck in recovery or their pics showed the itunes usb screen. Should I stay far away from those or can that be fixed? So basically, would it be a horrible idea to ever buy an iphone that is in recovery mode? If so, also what would YOU ask and need to know before purchasing an iphone fropm craigslist?
