Today Konami updated their popular iOS game Jubeat Plus to include support for the iPhone and iPod Touch!
The game is identical to the larger version but is on a smaller screen. It is still a 4×4 layout, same as the arcade and iPad versions.
Song packs purchased on the iPad transfer over to the iPhone, and vice versa.
The version of the application is 2.0.0 and it is compatible with the iPhone 3GS, iPhone 4, and 3rd and 4th generations of iPod Touch. It is not compatible with the iPhone 3G or iPhone
UPDATE: The game when running on iPhone/iTouch includes a calibration mode to adjust for finger size. In addition, the leaderboards are separate.
