I had some issues with the battery and got a replacement phone, which erased my jailbreak. Surprisingly, the iPhone came with iPhone 3.0. I don't want to upgrade to 3.1 yet and but want to jailbreak again to 3.0.1. What should I do? All the instructions and YouTube videos say "Upgrade from iTunes to 3.0.1," but I can't do that now. I tried hitting restore with pressing the ALT, but it says my phone's not eligible for it. Any ideas? Thanks.
