this happened to me and I just fixed it. first plug in your touch to the computer. then hold sleep and home buttons until it turns on and off and then the second the logo appears release the sleep button but keep holding the home button. this will get you into restore mode!
all you have to do is press the top button until it shuts completely off. Then you have to press the home button then it should turn on. you can also put it face down and step on the back of it and a white screen should appear then plug it up to I tunes and it should work from there
