1. The iPhone 3G, iPhone 3GS, and iPhone 4 models use A-GPS -- or "Assisted GPS" -- which in basic terms accesses an intermediary server when it is not possible to connect directly via satellite -- indoors, for example -- and this server provides the nearest satellite with additional information to make it possible to more accurately determine a users position.
   
2. 
   
3. Apple explains that the iPhone 3G, iPhone 3GS, and iPhone 4 also use "wi-fi hotspots and cellular towers to get the most accurate location fast" when GPS is not the most convenient method of location detection. The iPhone 3GS and iPhone 4 additionally have an integrated digital compass to also provide the direction one is facing, which is quite useful when combined with mapping software.
   
4. 
   
5. When combined with a service -- such as AT&T Navigator which "transforms your iPhone 3G, iPhone 3GS or iPhone 4 into a voice-guided GPS navigation system for traveling across the country and just across town" for an additional monthly charge -- theses iPhone models are capable of providing real-time navigation.
