I just had my USB cable replaced, and this is what Apple sent me... What is this new port in the back? UPDATE It's for the Apple Bluetooth headset http://www.ifans.com/forums/showpost.php?p=2660694&postcount=24
Is it me or is that dock connector huuuuuge. The one shiped with the latest products is really small. That looks way long, one thought that comes to mind is it may allow you to connect a cable to use for thunderbolt. But they would not make it that big, why go small then huge. May be a very old cable.
What ever you do don't tell Apple. I bet it is an unreleased cable with some weird feature... Nevermind blackmail Apple
On topic: Wow that is weird. Off topic: finally somebody who cut their fingernails before uploading pictures
BLACK MAIL APPLE!!!! <- solution to all your problems EDIT: Kinda looks like a MacBook charger. Could it be that you can hook it up to a Mac charger and charge it? Also did you buy this direct from Apple?
