I received the Gingerbread update this morning. It installed on my phone and then my phone basically became unusable. The screen would freeze and I couldn't do anything. I couldn't even turn it off. I would take out the battery, put it back in, turn the phone back on, and it would keep doing the same thing. Finally, I took out the SD card and it seems to be working fine. Why is this? Do I need a new SD card? Any suggestions?!? Thanks for your help!!!
