MapQuest 4 Mobile is an application that brings the eponymous mapping service to BlackBerry devices. MapQuest 4 Mobile can give you an interactive map of your current location (leveraging built-in GPS if your BlackBerry has it) and, of course, driving directions. It also offers aerial views, business searches, traffic updates, and a GPS-powered Find Me feature. The app is free; it’s currently available on Sprint for the BlackBerry 8830 and AT&T for the BlackBerry 8800, 8820, and 8310. Support for additional handsets is coming soon.
