Google Maps has been updated on my Nexus One, and while i can pan and tilt, the vector buildings are not appearing yet, even when viewing areas like San Francisco.
Maybe it requires Gingerbread. So Google where’s my cookie done?
[Update] My bad, you needed to zoom to the lowest 3 levels to see the vector buildings. Rotation, as advertised, does not work on Nexus One.
Disappointingly and unsurprisingly, Singapore does not have vector building data.
