If I try Deblet on a new MMC can I still boot to my HE2007, in my present mmc (change cards of course), using the same boot menu, or do I have to flash 770 again? E.g MMPC does not work on OS2006, so I still neeed HE2007. 770 is my only IT, so I have to keep it functional untill the next (hopefully 3G) version launch
