Trying to restore my FIL's iPhone 3GS which failed yesterday. It was unlocked with 6.15.00 iPad baseband. Problem is I don't know which software. It's stuck on white Apple logo and connect to iTunes. Jailbreak stops almost at the end or gets stuck on spinning wheel and white small square in top left corner. Any ideas? I tried tiny umbrella and it only goes through Apple logo and back to connect to iTunes screen. Help greatly appreciated
