Ok, so the other day I was taking a video with my iPhone 4 (jailbroken, firmware 4.1) when a message pops up saying i'm low on memory, so i try to end the video, but it just kinda freezes up so i press the home button not thinking too much of it. A few minutes later I try to go look at my pictures, but the app just keeps saying 'Please wait, updating library' then at the bottom it says 'rebuilding library...' then crashes a couple seconds later, the camera app does the exact same thing. I've tried syncing it to itunes, turning off the phone, hard restarting, and i'm just starting to get frustrated and overwhelmed, not really sure what to do at this point. I'm not really worried about losing pictures because i already backed them up on a flash drive, I just want a simple fix that won't unjailbreak my iphone. Sorry for my rambling lol, but any help or experience would be greatly appreciated.
