Taking a two-pronged approach in its attack plans for the iPhone, Taito is complementing its Space Invaders games on the App Store with a wave of themed cases, available in white, black, and red (each with different designs).

These limited edition cases are only releasing in Japan, but if you really have a hankering to show off your love of the classic arcade shooter (or the recently updated Space Invaders Infinity Gene), import shop NCSX has you covered.

The online store plans to ship preorders for the accessories in late November, and is asking $25.90 for each design. These are only for 3G and 3GS models, though, so if you have an iPhone 4, you'll have to settle for decorating your free case with a sharpie marker or Space Invaders stickers.
