I'm not sure but for some reason I thought I heard about Bluetooth keyboards, if so wouldn't they work?
a battery/controller case. slides over the iphone, plugging in and providing a dual stick analog controller and an extended battery at the same time. bigger games could be implemented with this, driving better titles more money and attracting more devs. apple has to make it tho, not a 3rd party in order for it to become widespread. or at the very least, promote and carry it in stores.
