Apple Dock Connector Port Pinout

[Mac128]

Anybody seen the latest dock connector port pinout? I understand it changed from the iPhone 3G to 3GS.

This one shows only the 3G.

But here's a question, why are all those Firewire data lines present? All iPhones and iPods use USB. Could they possibly be for future implementation? For instance, the iPad doesn't have a camera. But couldn't a simple swivel camera be attached to the dock connector to face front or back and feed Firewire speed video for streaming? Say a higher quality camera than Apple could afford to build in and hit their price points?

Have any jailbroken iPhones been able to access these data lines? Did Apple eliminate them in the 3GS?

my jail broken iphone can use firewire, but only to charge, not to sync.

FireWire's there because that's what the iPod 3G-5G, plus iPod mini used as 'primary'.

The original iPhone, along with the iPod nanos up to 3G, can charge over FireWire (even when not jailbroken,) but don't contain any data-transfer logic for FireWire. The iPhone 3G and iPod nano 4G+ can't even charge over FW. (Had to get a new car charger when I got my 3G.)

They may be able to re-use the FW data pins, but the power pins are off-limits. You don't want to have someone accidentally plug in a new device that expects those 12V pins to be anything other than 12V, into an old device that spits 12V out over them. (Like my speaker dock.) I'm just annoyed that newer speaker docks don't give out 12V "FireWire" power. My old 3G iPod works fine, other than a dead battery, and I'd like to get a new speaker dock; but none provide 12V power for it.

(The 3G iPod, the first one with the dock, will sync over USB, but not charge. It requires 12V FireWire power to charge. All newer iPods can USB charge.)

That explains why my car charger has been obsoleted...
