My iPhone 3GS is dying (it's an early 2009 model, so I've been expecting it). I'm trying to decide what to upgrade to. I found an iPhone 5 on CL for $200 that has issues, but I'm wondering if I can fix them. The seller says they bought it jailbroken, but now it won't boot after upgrading to iOS 7. Is this fixable at all? I've had some experience jailbreaking my 3GS, so I know it's pretty dumb that they upgraded to 7, but I'm assuming there has to be some way to get it going again. The seller sounded like they didn't have any experience jailbreaking. Thanks in advance!
