Take your iPhone gaming to the next level with the iControlPad. This controller lets you experience the full thrill of handheld gaming on your iPhone.
What makes the iControlPad so awesome is that it is so simple to use. Simply slide your iPhone into the serial port and voila. No software to install, no fuss, no muss. The iControlPad is set to be released soon. Looks like I need to sell my PSP and buy an iPhone.
