I have been looking for a good 3 party backup software. I would like the file to be a .ipsw file or some other file like .iso. That way I can use it to restore my iPhone back too the way I want it to be. I currently have a iPhone 3G running iOS 4.0.1 (8A306), firmware 05.13.04. I've seen some of the old forums but would like to look at the most up to date software out there.

Thanks InfiniteImmortal
