Doesn't the "G" stand for Global?

While traveling in southern Brazil I decided to give the 3G iPhone's new GPS a try.

I opened up Maps and asked for my current location. It took a while to load - I even had to wake up the screen once or twice - but the maps finally loaded and the blue dot appeared. It had me located on a street in Los Angeles, over 4,000 miles north west of my actual location. Maybe it should be UPS (USA Positioning System) instead of GPS.

A lot of other things went right, though. The 3G network was always available and as long as we hand fed it the address of our current location it did a remarkable job of providing directions for where ever we needed to go.
