Hey guys, yes this is the same question. I can't seem to restore my sister's iPod touch. I do everything while plugged in and it will try for about 2 minutes to prepare it for restore and an error will pop up saying iPod couldn't not be restored an unknown error has occurred. I have tried this like 5 or 6 times and it still won't work. I have tried it on my iMac, my sisters MBP and my mom's windows laptop, al yielding the same results. I don't know why it stopped working today and won't turn on, or restore on itunes. But she was just using it last night. What should I do? Please help. Oh and I'm getting my ipod touch in like a half hour woo hoo!
