I'm not sure what I installed on my phone, maybe rock extentions or intellishared and suddenly my photos app starts to crash when I swipe to go to the next picture or go back. The app works all fine until I swipe to go to the next picture or go back from a picture, then it crashes..

any ideas? except for restoring?
Also if I restore will I lose all my jailbroken apps and have to reinstall them all? is there a way to restore and keep everything as it is now, except for the photos app problem?
