Not sure why so many people are stuck on that.

Virtually all of my smartphones for years and years have actual GPS hardware. They do also include software to provide a location estimate from towers and WiFi if you are indoors out of GPS range in ADDITION to the GPS. Basically, they out perform a GPS by even working where a GPS can't.
In fact my current phone, a Samsung SIII not only provides location data from the US GPS system, but also from the Russian Glonass system. I'm indoors right now getting location information from 23 satellites (plus the cell towers and WiFi). Needless to say, location data is quick and accurate.
