After I install something, I can't just hit the home button and go home, it stays locked in Cydia. I can navigate around Cydia and continue to do things, but neither the power button nor the home screen button work. I just have to let it run and the iphone eventually force quits the program. I can't even get the program to force quit by itself. I am running a iphone 3g with 2.0.1 quickpwned. Thoughts?
