My sister's iPod Touch won't work right!

Hi there,

Okay. So.... I was playing around on my sister's iPod Touch, and I think I pressed something, because it went to the music albums, and I pressed the house button a bunch of times, but it just came up with a little window with a song's name and "Close" or "Music". Then, it went to the iTunes store and just kinda.... froze. I pressed the button at the top that turns it off and turned it back on again. Then, I slid the little touch bar, and typed in her code. It didn't go past that, and I clicked random numbers and "Unlock" or whatever and it didn't unlock. I turned it off and then back on again, and it wouldn't even type in any numbers. Turned it off then back on, and it just completely froze up; didn't even go past the 'slide to unlock' screen, and it's completely frozen up now!! You can turn it off and on using the little button at the top, but that's about it. We tried many, many times. Help....?!?!?!
