I notice every where I touch on my iPad 2 it registers the touch a little above where I touch. Is there some sort of app that will visualize touches so I can know if the calibration is off? OR is this an iOS 5 beta 4 issue? Anyone else with iOS 5 beta 4 notice anything like this? It's actually a problem using tabbed browsing, I always hit the top of a tab and instead it clicks on the bookmark above it in the bookmarks bar. Annoying.
