Hi all I hope you can help. My friend gave me his iPhone 3gs to jailbreak a while ago when we were still on 5.1.1. All went great at the time. Like most Ive upgraded to iPhone4 but he loves his 3gs so who am I to argue. 12 months on and its that time again, he has now passed it to me again and asked me to upgrade it to ios 6.(after reading the new update from redsn0w) I need to preserve the baseband because he needs to still use ultasn0w to unlock it. Plus he needs it untethered. I did all my homework as per usual. Its on the old bootrom (2009 week 29) Baseband is on 05.13.04 I downloaded ios 6 and redsnOw 09.15b3 from the appropriate sites. Ill cut a long story short, (as we all know how the rest goes) 09.15b3 allows you to retain your old BB without customising the ipsw, which is great, if I could get it to work. Half way through the upgrade while retaining the BB I keep getting iTunes error 1. Can anyone shine a light on this?
