I'm still on the stock FW that came with the phone. If I update to JH3, will it automatically format and reinstall (is it a full rom) or is it just an update? If it does format, is there a good app to backup my apps and such (would Titanium help or does that do a full restore including the OS?). Also, does anyone know a good app to backup/restore/transfer SMS? At the AT&T store, they transfered all my texts from my BB to this phone in a couple minutes but forgot to ask what they used for it.
