I recently jailbroke to 4.0 and I've been fairly satisfied with it. However, yesterday I noticed that my camera app stopped working indefinitely. I have no idea how this happened and I'm not sure if it was because I downloaded something new from Cydia. I tried to delete all the things that I thought might cause the problem but I was unable to find a way to fix the problem. What I have tried so far besides deleting new Cydia downloads is putting the phone into safe mode manually and testing it and I also disabled all themes. I also downloaded another camera app from the app store to see if it works but the app keeps on crashing, I really don't know what to do. Any tips on what I can do? I'm using an iPhone 3GS Edit: let me note that the app opens up to the point where the shutter shows up and then it turns to a black screen and goes back to springboard. I was actually able to get the app running for a few seconds about an hour earlier before it crashed.
