When I received my second 2.2 ota yesterday my phone kept freezing after booting up. Tried many battery pulls and same. Did a factory reset, no difference. I remembered reading in another post about reformatting the sd card. So, I took phone into verizon and they put an empty sd card into my phone and it worked! So, I erased (formatted) my card while the card was in my phone (quickly, before it froze...settings-->sd card and phone storage-->format sd card). Once again, my phone worked great. I reinstalled apps and configured my phone since I factory reset earlier...still everything was working great...the snappiest and most responsive my phone has ever been. Then I put about 6 gigs of pictures and music on my sd card....froze up again. So...curious if you all think it is a bad sd card or just the phone is jacked up and cant handle the data in the card. Also, is reformatting the card on a computer the same as doing what I did while the card was in the phone? I am hoping the guy I spoke with at verizon (who owns a droid) has a full sd card in his phone and would be willing to have me put it in my phone to see what happens, that should tell me alot. Thanks for any input.
