Upgrade to Google Maps API v2

Gosh, Maps API v2 is just so much nicer in every way. If we are going to stick with the Google Maps concept, then I would say Maps API v2 is a must.

Good call. I think at this point TTFT is going to stick with Google Maps as a proof of concept and practice, so we'll upgrade. At the same time, I still also need m APK so I can use the Google maps on my phone.
