Yet another update to the iPhone firmware 2.0 and the SDK have leaked out. The new firmware has been dubbed 5a308. that build was released today, along with a fresh build of the SDK. The new SDK is 1221.8MB, so it is a little bigger than the last release, which was the fifth such release. It is not known yet whether that is the firmware beta that adds the rumored geo tagging features.

The firmware is fresh off the server, and the details about it are few. What we do know right now is that the new SDK requires developers to register an application ID,

suggesting that they are tightening things up in anticipation of the launch, which is rumored to be soon. Application IDs are called for for provisioning now, all previous provisioning is now longer valid.

Another interesting thing is you must be running OSX 10.5.3, which was just released that wee hours. It is odd that Apple would cut off the still large amount of users running Tiger, or 10.4. The new updates release notes were uploaded to Apple’s site earlier, and can be viewed now. Apple plus removed six demo applications from the SDK package.
