Well my phone is jailbroken on 2.2, and I was playing on the GBA emulator, then quit it. I must have double tapped the home button, and it opened the iPod app. Now when I press home, it's not going to the home screen. but if I lock it, and press the home button, it wakes up. When I tried turning it off, the 'slide to turn off' thing never appeared. Please help!
