Apple has continued to add new features to their upcoming iPhone 2.0 firmware release. The latest version seeded to Enterprise customers has a added geo-tagging to the Camera application, according to Appleinsider.

The latest iPhone 2.0 Beta (5A292g) asks the user for permission before transmitting their location information. Apple currently uses Wi-fi and Cell tower identification to pinpoint locations, but is rumored to add GPS support in the next version of the iPhone.
This functionality appears to fall under a broader "Location Services" preference that can be turned on or off.Essentially, geo-tagging is the process of adding geographical identification metadata to media files such as latitude and longitude coordinates -- or even names of places -- so that those files can later be referenced, searched, and grouped based on their origin.
The use of location in mobile phone applications is a growing trend. iPhone developers are already working on location based social networks and even a multiplayer role playing game (MMORPG) set in the real world.
