Google Maps was updated to version 4.60 last week, and you may not have noticed it on the surface, but contained inside were some interesting resources providing an early glimpse at the style direction Gingerbread is set to take. Freenode IRC member canadiancow rather astutely spotted that there was a folder contained within the 4.60 APK that included icons and styling for API level 9, whilst we're currently on level 8 with Froyo. He changed all references to level 9 down to level 8 and recompiled the APK, and voilà, this is what Maps will look like (on left):
Obviously not a great deal has changed, but we are liking the new styling on the buttons, and the slight-transparency on the pop-up dialog. Hopefully this more-professional look is a hint at what's soon to follow.
[Thanks for the tip, CanadianCow!]
