UGH mine just did the same exact thing but mines not coming back to life... I've had it on iTunes nothing...frack frack frack that means i have to go deal with Apple at The Domain... someone just shoot me now! FRACK FRACK FRACK!
Thanks! That worked for me! Think it might have run out of power and become annoyed. I left it charging overnight as usual but fear my cable may have finally failed. For months it has had a section where the wires are exposed at the USB plug end but it still worked. I could only get it working by using my iPhone's cable and then once it had acquired some charge, it burst into life with the 15 second thing. Thanks so much for the tip!
