Long story short, got a used iphone 3gs from a friend who said it was factory unlocked, attempted an itunes restore which was unsuccessful and left the phone stuck in recovery loop with apple logo on black screen. So, i'm thinking the phone was probably jailbroken, which I probably should have checked out before attempting the restore, but I was in a rush and it's been a couple of years since I unlocked my old 3gs. The phone does not respond to a hard reset, but after the battery drains completely I can get it into recovery mode, tiny umbrella seems to recognize the device with some random number, but says the device model is "invalid" and the firmware space is blank. I haven't been able to get it into DFU so far. The serial number starts with 86016, so could it have the ipad baseband on it? is there anyway to know if it does? If i try to restore with itunes again will i be able to unlock it again?
thanks!
thanks!
