We're not entirely convinced by the name 22Moo, but now that iPhone OS 3.0 supports third-party peripherals we're sure we could find some bag-space for their GameBone Pro controller. Intended to be used with an iPhone or iPod touch, the GameBone Pro hooks up via Bluetooth or Apple's dock-connector, and has an 8-way D-pad plus six buttons.
There's also a 2,000mAh Li-Ion battery, which not only powers the GameBone Pro's functionality but - if you use the wired connection - can recharge your iPhone or iPod touch, too. A row of LEDs shows charge status.
The controller also has integrated speakers, a microphone, and a 3.5mm headphone jack. It's set to hit shelves in mid-September, but we don't know price yet; 22Moo are asking potential customers to suggest what they'd pay for the GameBone Pro, which seems like an obvious way to find your shiny new peripheral now costs fifty cents.
