The same thing happened to me, and what I did was I held down the home button and the power on/off button until the apple icon shown. But before the icon will show you may see a red slider bar. Do not let go of the 2 buttons until apple shows after. That will hopefully reset your frozen ipod touch. Another thing to do is to hold down the home button and the on/off button until apple icon shows then let go of the on/off button and hold on to the home for an extra 20 sec. I hope this helps!!
Best of luck!!!!!
