Camera issues

[mord.howie]

I was given an iPhone 4 unlocked and jailbroken. The only issue, the camera wasn't working. Did a reset off the settings. Didn't help. Did a hard restore. Also didn't help. When I open the camera app, it'll do one of two things. Either it will just stay with the shutter closed, or it'll open and stay black and it'll autofocus. Help?

1.Put the phone into DFU Mode and do a restore. (not sure if that's what you meant by hard restore)
2. Carry it to your local apple store
