Can anyone direct me to a (hopefully) free software that allows me to do just that? Long story short, I downgraded from my iPhone 4 to an iPhone 3G. The iPhone 4 backup was on 5.0.1 and the iPhone 3G won't accept it as the software on the iPhone3G is too old (Apple stopped their updates on the 3G at 4.2.1). I have tried EVERYTHING to no avail so far. Even tried the info.plist hack that tricks iTunes into thinking it's a 4.2.1. Any help would be greatly appreciated!
