I bought an i3G from someone at RadioShack tonight. Got it for $100 instead of them selling it for $75. So I checked the phone when I got it from her and it was on version 3.0.3 the update after the 3Gs came out. The phone had also been jailbroken. Either way she done a "Erase all contents and settings", and the phone said it would take about an hour. It done the same thing my 3G I sold the other day done, but when it was done it is now stuck on the black screen with the picture of the apple. Doesn't have anything above it like PWNED, or any other noticeable jailbroken stuff. I figured I would do a factory restore on it, but wondering if there was anyone out there that had any other suggestions. Or should this work? I hope I can get it fixed and working so I can sell it and make some money. What could have caused this, or is this common in previously jailbroken phones.
