Google Maps looks stunning in this Apple iPhone Guided Tour Video. However there is no built-in GPS in iPhone. Why?
The Nokia N95 and the Blackberry 8800 Series have embedded GPS support but reviews are saying that they cannot deliver reliable positioning just yet.
Is seems that GPS enabled phones are not up to the challenge of replacing standalone GPS navigation devices. There’s no need to throw away your Garmin or Magellan just yet. If you are looking for a phone with built-in GPS that delivers reliable positioning you might need to wait a bit longer.
