I added a repository on Cydia today (wasn't even installing any software!); it got stuck on Downloading Packages. After about 20 minutes of idling, I rebooted the iPad. After the reboot, it came up normally to the password screen. I entered in my 4-digit password, and then the iPad rebooted again. Post reboot, the GUI is distorted. It's like it has reverted to an iPhone. It only has four icons across and all of the icons are small. Anyone seen this before? Is there a fix?
