Well I'll try and keep this short. I've got an iPhone 4 with 4.2.1 I was at a concert tonight attempting to film the performers. My phone began to lag but didn't want to restart it because it would be my only chance to film the certain song. So I get the last minute of the song and the performers walking off stage (About 3 feet away, so this was a pretty exciting deal at the time) I stopped recording and pressed the sleep button. I walked back to my seat and pulled out my phone to make sure the film had saved. However, my phone had restarted and was on the Apple logo. When it started back up, I opened up my Photos app and it said "Rebuilding Library" which took about a minute or two. When it was finally done my video was gone. Is the video officially gone? Or would it be somewhere in the back up? Of all the footage and pictures I got of tonight's concert, that's the video I had hoped to keep the most. Any help would be wonderful!
