hey im a new Droid user with an original Droid i just recently upgraded to froyo(2.2) and am interested in learning how to make an "advanced nandroid backup" for 2.2 - i would like to make a back-up so i can try out different ROMs like Sapphire and boost my cpu speed my current Quadrant high score was a 870 but averages around 780. would like to see 1000 and maybe some better battery duration.
