Apple beta testing iPhone 2.1 firmware, adding more GPS features

We just got word that Apple has released a beta version of iPhone OS 2.1 to developers. Along with the 2.1 firmware, a new version of the iPhone SDK has been seeded as well, but the new SDK can’t be used for submitting applications to the App Store at the moment.

A few new things we are seeing in this version of the software is the addition of a bunch of Core Location features that track the direction you are heading, and the speed you are traveling. Looks like we might see a turn-by-turn GPS app after all on the iPhone 3G.
