Ok, I recently tried Unlocking my iPhone 3GS (5.15.04) using the methods described: http://www.ihackintosh.com/2010/11/dev-team-releases-ultrasn0w-1-2-unlock-for-ios-4-2-1/ - using pwnagetool Not sure if theres a trouble shooting guide for this, Heres what I do: - Downloaded Pwnage Tool 4.1.3 Unlock Edition, iOS 4.2.1 for iPhone 3GS, iOS 4.1 for iPhone 3GS iOS iPad 3.2.2 -Then Launched pwnageTool, after I select the 3Gs, it prompts me to locate the .ipsw-IT DOES NOT RECOGNIZE ANY 4.2.1 ipsw. It DID recognize a 4.1 restore (iPhone2,1_4.1_8B117_Restore.ipsw) And So from there I followed the steps and then Restored it through iTunes. THEN- iTunes always stops saying "could not be completed because of an unknown error #1063" - Not sure if this is because tyring to use 4.1? Then I tried downloading a custom 4.2.1 with the iPad base included - and I get. "Could not be completed because not eligable for the requested build."' Is there anything that can be done? Any ideas? Hope this wasnt too much of a pain - thanks in advance.
