Im sure this is a very stupid question but I want to be sure before I mess anything up... I have a 3GS running 4.0.1 and modem firmware 5.13.04 and the old bootrom.
I want to upgrade to iOS5 and unlock it. I understand that I can use the Redsn0w jailbreak and then unlock using UltraSnow.
1> Will I be able to successfully do an unthethered jailbreak with the latest RedSnow?
2> Will I be able to follow that with a successful unlock using the latest UltraSnow?
3> Will this method mess up my baseband?
Please help me out. I would really appreciate it.
