Google has launched MyLocation, a nice tool for mobile maps that triangulates your location based on your distance to cell towers.
A blue dot and a circle are placed on Google mobile maps that show you where you are and eliminate the need to type in a geographic modifier when looking for things around you. The technology is accurate within 100 meters on average and will work on BlackBerry, Windows Mobile, Nokia/Symbian and Java-enabled phones. Ironically, this doesn’t apply to the Google Maps application built into the iPhone.
Check out a video on the new feature at the link above. I’m also talking to John Hanke, head of Google Maps and Google Earth, tomorrow at ILM:07 and will be sure to ask him more about it.
