OK I think I see the confusion. Most android phones have memory in 2 places, the internal phone (which you cannot really access without root and you cannot edit) and the external sdcard (the sdcard you put into the phone). Well on the Atrix, you have 3 locations. The internal phone where the system and data files are (again which you cannot really access without root and you cannot edit also you are not backing up these); the internal sdcard, this is also internal memory but is memory set aside like an sdcard, this was done so AT&T did not need to include sdcards with the phone and then you have the external sdcard, this is one your purchased and put into the phone. Gingerbreak erases the internal and external sdcards, it does not touch the internal phone memory. If you open the app called "files" you will see Internal phone storage (that is the internal sdcard not the phone's system or data files) and SD card which is the sdcard you purchased and put into the phone. So you are backingup your sdcards not the phone Since Gingerbreak will not touch the internal memory (well it does add root) your settings and everything is ok. The issue is if you have apps installed on your sdcard, they will not work until you put the files back on the internal sdcard.
