Gearlive reports that Apple has released OS 2.1 beta 1 along with a new SDK version for development purposes. The SDK is said to add additional Core Location features like heading and speed.
This might be a hardware feature of the GPS chipset as well as a software feature (just by calculation of differences between two locations). Unfortunately, Infineon still hasn't sent me any data on the Hammerhead II upon my inquiry, so I can't tell.
What I can't tell either is what is to come in the new SDK as it isn't available for me through Apples developer program yet. Also, the Core Location framework still shows old version numbers.
I'm curious if there's a way now to determine the origin of the location data.
