I kind of feel like you do. At some point, i would like to try it, but i'm not splitting the hard drive on my Mac, and i don't know anyone with a PC, who would let me use it for the purpose of rooting.Am not rooted, mostly because of security and secondly because I don't see the need. Android is already as open as I need it to be.

So how are nandroid backups made? And okay thank you! Is there a difference between I747U and I747M as far as rooting/roms go?
