Actually, GPS should NOT be a hardware change. All current phones are required by FCC rules to be able to pinpoint a caller's location to within some distance for 911 calls.
The FCC rules don't require GPS hardware; they simply require that a carrier be able to locate a phone, as you note, within a certain distance. As I understand it, for many phones the carrier simply triangulates the location using the closest towers.
And even if you ignore that, you can easily add GPS capability by way of Bluetooth.
Sure, but that requires a separate receiver. Our wish was for built-in capabilities.
And I think it's only a matter of time before most phones have such a feature. I personally think standalone GPS units will be limited to things like cabs and truck drivers before too long. It makes too much sense to include GPS functionality in a phone, provided it has a big enough screen.
