It looks like the iControlPad may be getting some real competition, real fast. Game-Gripper is a new concept for adding real gaming controls to smartphones via a universal clamp-on hardware game pad. To ensure compatibility with as many devices as possible, the Game-Gripper attaches to your phone via a spring-loaded clamp to hold the device in place, and it relies on Bluetooth connectivity rather than physical I/O ports so there's no need to worry about which phone you have. The website flaunts a number of Android phones, apparently already compatible with the device, as it relies on industry-standard Bluetooth HID profiles to remain friendly with just about any phone. iPhone compatibility is mentioned here-and-there, but no solid claims are made, as compatibility with individual games and emulators relies solely on the developer's willingness to implement support for it.
