i'm trying to figure out the best backup method as well. i'm on the original froyo ROM, but all these new ROMs keep coming out with new features. but everytime i flash a new ROM i will lose my call logs, texts, etc. i just dont want to start over AGAIN.
of course i do nand backups, which is a total 100% image backup. but its not possible to, say, nand backup on cyanogen mod, then install froyo and restore the cyanogen nand to the froyo, right? that wont work? i assume it would either crash and not work, or it DOES work but just put cyanogen right back on the phone exactly the way it was, thus losing the froyo ROM update in the first place. any advice?
