Ios5 Whitescreen.

Okay, my ipod has crashed and I need help from someone good at fixing stuff like that. I was innocently viewing a twitter post, when the screen froze and my ipod became unresponsive. It stayed like that for 30 seconds, and then it changed into just a white screen. It has been in an unresponsive whitescreen state for half an hour, and I am getting worried. My current plan is just to let the battery run down, then charge it and see if it works again. If it doesnt, I will send it back. Is there a better way to fix it? Do you know what the problem is? If you can help, please reply.
