Just a heads up that company that sells the iDevice interface has them back in stock. I was originally going to purchase the thunderbolt version then made aware they have a USB version too.
I'm thinking I can plug both my android or apple devices.
I have nothing to do with this company thought I would share since they were out of stock recently.
The IL-BKR and USB-BKR iPhone/iPod adapters.
