Argh! So this replaces user data etc? ie All apps and settings will have to be reinstalled? Or Will a backup and reinstall after R7 goes on save me the hassle?
Do an 'erase all content and settings' from Settings -> Software Tool, and once it reboots, install the ROM.
not bothered either way, as I would rather spend extra time making sure it works perfectly - but would love to avoid the hassle of reinstalling apps 1 by 1 if poss!
