BCollins521 has created some really nice Themes for the Tour. Head over to MobiHand or CB to check them out...
Vista BB Edition v1.0 to 1.2 by Theme Addiction
Tiger Berry OSX v1.0 to 1.2 by Theme Addiction
bDroid v1.0 by Theme Addiction
Tiger Berry OSX is really nice looking theme, BUT when i installed it my Tour hanged twice - only buttery pull helped (it never happened before on default theme). Unfortunately, this theme is not completely bug-free, switched back to default.
