I am having the same issues with my camera that I had with the earlier versions of Mighty4. I made a thread about it here:
http://forum.ppcgeeks.com/showthread.php?t=71170
Fresh flash, also hard reset, installed interface changing apps and cabs, no reg tweaks, I have the same exact problem. The phone I have now is a new replacement, not the same one I had when I posted that thread.
(If only I can search for specific posts in specific threads, this one is way too long to browse through)
