I have an iPad2 (might be a 3) - not jailbroken - that is locked up, with a broken home button. I am getting the "iCloud backup" dialog box that wont dismiss. If the home button was working, I would simply hold home/sleep for 10 seconds. I tried to backup, but the device does not recognize when the cable is connected. It will not see the computer (tried two different win7 machines) nor even the stock wall charger. I guess I could wait till the battery dies, but since its at 98%, and it goes into sleep mode in a minute, this might take a while. Please help!
