Applications update frozen at "waiting"

When I selected "update all applications" on my iPad, it showed "waiting" and has been frozen there for the last 2 hours for all applications!! I've tried hard reset of the iPad but it still shows the same greyed out "waiting" for all my fav apps. Thinking it was a wifi problem, I tried downloading a couple other new apps from the AppStore. Now those are frozen at "waiting" too. I can't seem to uninstall before reinstalling again either.

I've never experienced this with my iPhone. What's wrong? Help!
