It messes up a lot.
My main complaint is that it gets confused about which tab I have open. When youre looking at all the different tabs thumbnails they seem correct. Once you tap one, however, it very often loads the first tab (the one at the top left) before it loads the correct tab. My other minor complaints or that its ugly and its default web browser is Yahoo. Ive used the browser for about 20 mins in total. Going back to Safari now.
