After upgrading my iPhone 4 to iOS 5 beta 2, my camera no longer functions.  The on-screen "shutter" opens, then immediately re-closes and won't re-open.  The issue has persisted across several restores, including going back to beta 1 or 4.3.3.  Has anyone else had this issue, or figured out a fix for it?
