My iphones camera shutter won't open
What it looks like when I open my camera app is a closed shutter and the camera/video slider flashing very fast. I can still click the photo thumbnail in the bottom left corner of the camera app and go to my camera roll and that's it. The camera works fine with other apps that use it so it's not a hardware problem.
I called apple and since my phone is out of warranty they won't help me. I thought maybe if I clicked restore in itunes it would fix it but I'm not sure if it will erase all my data or not which I don't want. How can I make it work again? right now I'm fine with ios4 (jailbroken for a year now working fine) but I hear there is a stable jailbreak for ios 5 now so I might upgrade, will upgrading maybe fix it? finally, how can I make a copy of all my stuff in a seperate folder? I want ALL my music, photos, videos, notes etc. in a folder that isn't itunes because I really don't trust it and I've heard enough horror stories of things getting wiped clean to know I should make a hard/original backup of everything.
