Usually I put my USB Stick in my camera connection kit and open iFile. But since some days it did not work. My iPad 1 is a Redsnow 4.2.1 and I didn't changed anything. I only did some cydia updates of some programs. I don't know if the iFile was in the list of updates. I installed Backgrounder, but I don't think that this is the reason. could you please help me?
