I'm absolutely 100% sure you're tired of seeing these help me, I can't do this messages, but I have another one for you. Anyways, I have an iPhone 4 running iOS 4.3.3. I use it with a Turbo SIM and need to preserve my baseband to run iOS 5. I would like to upgrade to 5.0.1. I've followed numerous tutorials online, and the part where I always get stuck is introducing the ISPW of iOS 5.0.1 to Redsn0w. Redsn0w always comes back saying the firmware is unsupported Tutorials like this say to just point redsnow to iOS 5.0, but if I do, iTunes won't restore from it as it's not the newest version of iOS. http://www.ijailbreak.com/how-to/pre...os-5-baseband/ What am I doing wrong? EDIT- I know there is another thread on this, but as far as I can tell it does not properly address iOS 5.0.1 for my scenario.
