iPhone 2.0 code mentioning GPS support?

Apple has built in hooks for iPhone GPS features that aren't possible with the current hardware, according to a third-party plug-in support for Aperture 2.1, Apple this week has released the Software Development Kit (500KB) for the photo management software.
The platform lets programmers write code that adds new features for editing and exporting images handled inside the program.
A number of extensions from outside companies have already been made available on Apple's developer site for Aperture.

Revelations from the device emulator included with Apple’s current iPhone SDK indicate that the company has added support for true GPS hardware to the platform. This functionality could show up in the form of built-in GPS hardware, a dock-connected peripheral, or not at all — but the software is ready.

As discovered by user Steffen Voigt, the locationd component of the current iPhone emulator includes references to NMEA. NMEA is a data specification for communication between various location sensing devices, particularly GPS units.
