I was jailbreaking my iPod, but after Quickpwn told me to close my iPod, then hold the power and home key, and then release the power, it said it was sending the data, and nothing was changing. I came back 10 minutes later and it was on the same screen, so stupidly i unplugged my iPod. Now it won't turn on, and I'm really nervous that I might have broken it. Does anybody know how to fix this?
