Hi All, I know it is not possible to JB the newest Update. But please read my story to help me out! I JB & unlocked a 3GS iphone w/ 3.0 on it. I sold it to someone overseas, who updated (ahhh!!) the OS to 3.1.3, and now the phone is pretty much useless. Is there anything I can do to help him get the phone restored in any sort of way? If i send him a prepaid-AT&T sim will that help at all? I feel bad so I wanted to help him out in anyway I can. Any thoughts/ suggestions are greatly appreciated. Thanks!
