Extending the USB–Lightning cable
I have a lovely new iPad mini Retina. The USB-Lightning cable that came with it is very short. I'd like to extend it. I assume the simplest (and probably cheapest) way to do this would be to get a USB extension cable, one with a female plug one end and a male the other. Correct? If so, do I need USB2 or USB3? I'm guessing 2, but not sure.
