A low-level code grovel of OS 4.0 has unearthed some intriguing functions — which suggest Apple may have a branded iPhone automobile mount in the works.
OS 4.0's "iPod Out" feature — reportedly designed to be used with the iPod Accessory Protocol in automobiles — includes the strings "IAPSSimpleRemoteCarButtonNotification" and "IAPSSimpleRemoteCarButtonTypeKey." In non-hacker dummy speak, this would allow external control of an iDevice — for instance, via a car mount with both control buttons and a video screen for menu display.
Another code string ("kCTCallStatusChangeNotification") suggests the ability to answer incoming calls without touching their iPhones.
An official, full-featured Apple iPhone car kit could spell big trouble for third-party manufacturers, whose mounts either add little additional functionality or (as with the Tom Tom car kit) are for a very specific purpose.
