Google has released an updated version of Google Maps Mobile (2.0) that includes a “my location” feature in addition to the proven mapping goodness. The jerry rig GPS uses cell towers to approximate your positioning. I tried it on my Blackberry, and it was eight blocks off from my actual position — but still pretty good for my general vicinity. You’d be screwed in areas with zero cell phone service, but cool nonetheless. Here’s hoping accuracy increases once the application leaves beta.
