Google wants to get more accurate with their Google Maps and their turning to WiFi to help them out. Traditionally, cell phone towers are used to pinpoint your location on Google Maps in the absence of a GPS satellite, but since the range of WiFi is much smaller than cell phone towers, WiFi access points give a more accurate location. The new feature called My Location with Wi-Fi will first become available on BlackBerry devices, with the Android OS and other systems getting their fair share of upgrades soon.

While it is available in major cities across the globe, Google is quick to note that the coverage and accuracy will vary, so don’t expect it to work flawlessly. So, what does this mean? If you’re using a BlackBerry, update your Google Maps for Mobile now to enjoy the WiFi-flavored goodness.
