Pogue on iPhone GPS

The New York Times tech guru is not impressed:

The new iPhone has true G.P.S. now, too, in addition to the fake G.P.S. of its predecessor — an ingenious system that shows your location on a map by analyzing nearby cellphone towers and Wi-Fi hot spots.Unfortunately, there’s not much you can do with the G.P.S. According to Apple, the iPhone’s G.P.S. antenna is much too small to emulate the turn-by-turn navigation of a G.P.S. unit for a vehicle, for example.

Instead, all it can do at this point is track your position as you drive along, representing you as a blue dot sliding along the roads of the map. Even then, the metal of a car or the buildings of Manhattan are often enough to block the iPhone’s view of the sky, leaving it just as confused as you are.

On the whole he says it's a nice upgrade, but much of it comes from the new apps, which can run on the old device.
