I want to update my iPhone currently running 4.0.1, jailbroken with jailbreakme.com to iOS 4.1. I am going to use PwnageTool to do this - can anyone tell me what it does exactly? If I understand correctly, all it does is put 4.1 on the device, already jailbroken, and everything else (AppStore apps left as they were, same order and all, jailbroken apps [like MyWi, etc]) stays the same. Is that right? I'd prefer not to have to resync all of my music, apps, etc and then put everything back the way I had it, so will using PwnageTool allow this? Thanks.
