What You Didn't Know About the iPhone 3G's GPS

From Gizmodo -


The problem with the 3G iPhone's GPS is, like most phones', the inconsistency in getting a solid signal, especially when indoors. So like most GPS-equipped phones, it uses assisted GPS, also known as aGPS or A-GPS, though it can mean a couple different things. In the iPhone's case, it means location is determined with a combo of GPS, Wi-Fi and cell towers. This actually makes it faster and alot more battery friendly too.

But hopes for a more robust navigation app from one of the majors like Garmin, TomTom or Telenav are foggy right now. But these could talk to Apple directly to get their apps on the iPhone, which would be smart for both parties. It'll make the iPhone an even more serious GPS device, and it'll give the established makers a piece of the pie they fear losing.
