You can get your first taste of Gingerbread through Google Maps version 4.63
According to Freenode IRC member canadiancow, Google Maps 4.6 has a few icons and UI styling for Android's API level 9 that are indentified with Android 2.3. Just to illustrate, Froyo, being Android 2.2, is correspondent to API level 8, while Donut (Android 1.6) is corespondent to API level 4.
canadiancow decided to change the build.prop file and managed to unveil the new UI styling of Android 2.3. You can see on the pictures below the difference between the two (left – Gingerbread, right – Froyo).
This is a little bit like the Cow Level of Blizzard's Diablo – not a big deal, but still nice to see and a first taste of the Gingerbread flavour. We hope we will see its full capabilities very, very soon.
