I had been browsing on an app, the app had a pop up add and when I clicked the 'x' to escape, the app froze. Now this app does this every so often so it wasn't a big deal. Now when I closed out the app, the ad was still in my background, even though all my homescreen widgets were up. Now I figured a simple restart was in order, so I did, all was going normal until it hit my carrier screen. It has been stuck for a half hour now, and the phone is less than two months old.
