Visiting MapQuest.com will now mean automatic location detection for Android users with GPS-enabled devices. As long as GPS hasn't been disabled for m.mapquest.com, users will be prompted to use "Current Location" instead of needing to manually type in an address.
The update is for devices using Android 1.1 or higher. There is support for Google Gears, but it will still work on Android 2.0 or higher, which does not use Google Gears.
Lately, data has been showing that Android has been growing at a nice pace. It's smart for entities such as MapQuest to innovate for the increasingly popular mobile OS.
