A friend wants me to jailbreak his iPhone, hes still running 3.0.1 and never got any of his files backed up into Cydia (also never been jail-broken before). He wants to preserve the baseband for ultrasn0w. He is on windows so non of the Mac utils will be of any use. I know blackra1n will jailbreak 3.1.2 but it will update the baseband. How can he jailbreak his virgin 3.0.1 3GS and preserve the baseband on Windows ?
