With the advancement of gaming on the iPhone, it’s no surprise that Ion went ahead and made buttons to help with the change.
The frustration of having to use a virtual d-pad/joystick on an iPhone has finally come to an end, thanks to the people at Ion.
The iCade Mobile is, in short, a controller adapter for your iPhone, featuring a joystick and four buttons. The controller works via Bluetooth as a cradle for your iPhone.
The iCade mobile works with the iPhone 3G up to the current iPhone 4S, along with both third and fourth generation iTouches.
