I'll be receiving my MID7127 tomorrow and I'm a little worried about rooting it. Can I make a backup before rooting, and if so how? I'd like to be able to do this in case I screw something up, also if something were to happen to it and I need to have warranty service, I'd like to be able to return it to factory settings. Any help is appreciated. One more potentially stupid question...If I were to need the backup, how do you actual access it and reboot the tablet?
