Two other patents published are directly related to Apple's iPhone Maps + Compass capabilities as follows: “Location Sharing: Abstract (patent application 20090325603) – Apple patent looks remarkably similar to Google Latitude's functionality, which Apple relegated to WebApp status earlier. If Apple is working on their own version of Google Latitude, may that's the reason behind the rejaction of the app. In Apple's implementation, it looks like the location data can be carried in an SMS or Instant Message (interesting news in its own right), which can then be opened in the Maps application to show the other person's location relative to the iPhone user's. Also, note what appears to be another instance of a front-facing camera on the iPhone image below. We're calling it now: iPhone 4G (and tablet + maybe iPod touch) get front faing cameras,” notes Seth Weintraub.
