I got an ipod touch yesterday, plugged it into my macbook pro, charged it and put some songs on it. Today i turned it on and found it unresponsive because the little white loading circle is in the middle. it says "slide to unlock" but i can't do anything while it loads. so it loads for roughly 5 seconds and then stops for 1 second before locking up and loading again. every time it locks up it goes back to " slide to unlock" so i don't even have enough time to turn it off. its really frustrating. does anyone have any advice? it would be greatly appreciated thanks.
