iPhone camera not working after installing Camera Genius

camera now working2 camera not working

Now this is really funny, I lost one of my 2G’s last week and now another iPhone (and the only one remaining) in our office has a camera issue. It runs v3.1.2 and after installing Camera Genius, the camera stopped working. The app launches but the shutter doesn’t open.

Restoring and jailbreaking again doesn’t help. Anyone with advice on what to do? Also, wondering if this is a hardware issue?
