Ok my iPhone 3GS has 3.1.3 installed and jailbroken with Spirit.

Everything is running lovely, but today went to use the video camera function for the first time and it doesn't work. When I press the record button, it doesn't do anything, but the button does get greyed out. If I exit the camera app after pressing the record button the whole phone is slow and I have to turn it off and on to solve it.

Photo camera function works fine.

Anyone know a fix for this?
