QUOTING THE BB8800 SITE:

"The BlackBerry® 8800 comes with a built-in Global Positioning System (GPS). Use it with a mapping application like BlackBerry® Maps and you can view your current location with greater accuracy and track your route to your target destination.

Built-in GPS also gives you access to a wide range of other Location-Based Services (LBS), like employee and resource tracking, social networking and more."
