I had the damnest time trying to get 2.2 on my droid but never had any luck. It would completely lock up and I would have to go back to 2.1 and everything would be ok. So I backed up my cd card to my computer then used the droid to format it. Used rom manager to install bb.4 and it ran beautifully. Scored 1520 on quadrant. So tonight I transferred my music, pictures and videos back over to the phone. Then it froze a couple mins after power up. I used it to post this but I have the sd card unmounted. Any ideas? Corrupt song? Phone says 7gigs free on the sd card and over 150 internal.
