The 16GB i-USBKey for iPhone and iPad from IUSBU transfers files from a PC, Mac or USB-equipped tablet computer to your iOS device, or from an iPhone to an iPad or vice-versa. It features a USB 2.0 connector for insertion into the computer on one side, and a 30-pin connector for your iPhone or iPad on the other. Move the switch on top from one side to the other to retract one plug and slide out the other. When the USB key is inserted into your iOS device, the i-USBKey app starts automatically if it's already been installed. If not, you can download it from the Apple App Store.
