My iPhone has stopped taking pictures in color. I've tried using the stock camera app, as well as camera+. Whenever I open any camera app, it starts on color for about a second, then goes into black and white, and won't take color photos. I am jailbroken, but I've tried started the phone in safe mode to disable all tweaks, and it's still stuck in b&W. I'm trying to exhaust all options before I just restore. Help please..
