Thanks everyone for your feedback after the Gingerbread update. Since there are several people having this same issue, I would like to submit feedback to our product team for this issue. Can you please send me a PM with your MEID, software & baseband version, and how often this happens? Those can be found in Settings>About phone. I only need a few examples, so just the people that have already posted in the forum please PM me. Once we have a product issue submitted, our product team will work with Samsung to duplicate then resolve this issue. 

Thank you,
