[Thanks to commenters so far, I've built in what you guys have noticed. To get Google Maps for Mobile 2.1, go to m.google.com on your S60 smartphone and follow the "Google Maps (Download)" link]
Changes for v2.1:
- Zooming in and out is slicker/clearer
- Several speed improvements
- Favourites sharing with Nokia Maps, Route 66, and others
- Tweaked menu structure
- Route junctions are shown with a diamond icon
- Extra languages are supported
Any other improvements anyone's noticed?
