Hi. I recently updated my 1.1.4 iPhone (original) to 2.2.1. It went fine but I had a bit of trouble getting DFU mode to work because of OS X 10.5.6. Has the DFU problem been fixed with 10.5.7? Also, would I be okay updating to 3.0 with Pwnage Tool? Would I be able to restore from backup in iTunes most importantly once using the custom firmware? Does restoring from a backup save restore all my game saves and texts... basically everything? Thanks!!!!
