If you enjoy being stalked, does Apple ever have a treat for you! The latest build of the iPhone OS 4 beta includes geotagging capabilities. According to Macnn, the latest build of the OS 4 beta includes a mobile version of iPhoto's Places that will allow iPhone users to geotag their photos and view photo locations without having to first sync to their computers.
AppleInsider was able to wrangle up a few screenshots of the Places interface, which upon inspection, would seem to share a lot of similarities with iPhoto's version of the feature.
Whether or not the feature will be included in Apple's final build of the operating system, however, is anybody's guess.
