Currently, running an iPad 16GB Wifi only model with iOS 4.3.5. I have been noticing some slow redraw issues using Safari, generally when scrolling down length pages. I am seeing the checkerboard background, then the page renders. Would upgrading to the latest version of iOS fix this or make it worse?
Is there a way to roll back to iOS 4.3.5, should I find iOS 5 latest version to be worse?
