I have a 1st gen iphone that was jailbroken once upon a time but after it setting for maybe 6 months I turn it on and it starts up with a pinapple as normal but then goes to the steve jobs cartoon thing. It comes up in itunes sometimes and I try to restore it to 1.0, 2.0 and 3.0 but they all fail with the error the iphone can not be restored, any suggestions?
