All was good on my JB iPad 2, I went looking for a cellular data metering app, found one on Cydia (can't recall the name, it was the one with free trial then a few bucks to buy) installed it, then it prompted to reboot. After rebooting, the lock page came up fine, but the home screen looks very different, (the logos spaced differently and not all ), and when swiping to the left to the search page, an iPhone keyboard comes up. I fear I may have installed an iPhone only app. Worst of all, when I click on any app, the screen switches for a half a second, then freezes, then the iPad reboots. This happens on every app I've tried, including Cydia. I just bought this last week so I don't have my SHSH blobs to do a 4.3.3 restore. Am I screwed? Is restoring to iOS 5 the only way out?
