I just noticed this today. I'm running FW 1.1.2 and I installed Touch Roll so I could use the Photo app to view the screenshots I took with the Capturerate app. Everything was working fine untill I tried to add an event to my calendar and noticed that the add button had disappeared. I installed the calendar fix intended for FW 1.1.1, but that fixed the calendar and made the Camera Roll in the Photo app disapear. I finally uninstalled the calendar fix and Touch Roll and my calendar went back to normal. Now I just have to use the Mobile Finder/Mobile Preview apps to view my screenshots. I was wondering if anyone else ran into this problem?
