Wondering if anyone has used or can verify that it is possible to use an OTG lightning cable to use a USB thumb drive with the iPad 4? I can find the cables online but nothing from anyone that says it works, and I hate to spend money on something that doesn't work. This is what I am wondering about. http://www.walkmancable.com/lightni...-for-ipad-mini-ipad-4th-generation-white.html
