[Maced] Another iPhone Question

Hi Kel
This is what the website says:

"GPS technology and iPhone software come together to create a new  
dimension in mobile phone mapping. Get a fast fix on your location.  
Track your progress as you go. Use applications that take advantage of  
GPS navigation features. All from iPhone 3G.
How it works.
GPS (Global Positioning System) technology uses information from earth- 
orbiting satellites to find locations. A receiver estimates the  
distance to GPS satellites based on the time it takes for signals to  
reach it, then uses that information to identify its location. But the  
A-GPS (Assisted GPS) solution on iPhone 3G goes a step further, using  
a unique approach to find the closest satellites and more quickly  
identify your position. That gives you a faster fix on your location  
than with regular GPS.

Get the signal.
In addition to A-GPS, iPhone 3G uses signals from GPS satellites, Wi- 
Fi hot spots and cellular towers to get the most accurate location  
fast. If GPS is available, iPhone displays a blue GPS indicator. But  
if you’re inside — without a clear line of sight to a GPS satellite —  
iPhone finds you via Wi-Fi. If you’re not in range of a Wi-Fi hot  
spot, iPhone finds you using cellular towers. And the size of a  
location circle tells you how accurately iPhone is able to calculate  
that location: The smaller the circle, the more accurate the location.

Stay on track.
Maps on iPhone 3G use GPS to help you get from point A to point B.  
Find a location, get directions and, if you like, follow your progress  
along a highlighted route with live GPS tracking.Learn more

Get apps that map.
iPhone 3G provides GPS-powered location feeds to built-in applications  
as well as to applications available on the App Store. Take a photo  
with the camera, for example and iPhone can geotag it with GPS  
location information. That way, when you share photos online, friends  
and family can see where every snapshot was taken. And you can shop  
the App Store for GPS-enabled applications such as mobile friend  
finders or interactive city guides.Learn more

Save power.
GPS on iPhone is active only when you need it. iPhone powers the GPS  
unit on and off quickly and automatically, so it won’t adversely  
affect battery life.
