Hello! I'm new and need help! When I got my iPhone 3GS it worked great. I sync-ed with iTunes and it wanted to update everything. That took a while & my laptop battery died during the backup process. It erased everything and I had to reinstall all my apps & music. Well now the orientation doesn't flip automatically anymore (stays on portrait mode) & I can't find a setting for it. Is there something i can do myself, or Should I take it to the AT&T store to see if they can fix it?
