Device Freeze

I picked up a touchpad after following webos for a long time, all the while really loving the OS but bot finding any of the phone offerings desirable. Then HP started the firesale and I couldn't resist.

Anyways, I downloaded and installed the 3.0.2 update. Everything was fine. I took it with me on my first day of clases and all worked as it is supposed to.

Then I got back to my room. I could unlock the device but no apps were opening. I dismissed all cards, turned off Wi-Fi, but it's still unresponsive. It registers touch input, I can open the app drawer and flick around, but nothing opens when I tap on the icon.

What do I do now?
