Another Apple patent today looks remarkably similar to the functionality of Google Latitude which Apple relegated to WebApp status earlier this year. Obviously if Apple is working on their own version of Google Latitude (or owns the IP rights to this functionality), they'd be hesitant to put an app with the same functionality on their devices from another company. Now it all makes sense!
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. Who is with us?
