Nokia has released a Pro Series Golf theme for all N-Gage-compatible phones (it should also work on other Symbian S60 3rd Edition devices too). You can download it from n-gage.com, and install it using PC Suite. It's been available unofficially on the MOSH service for quite some time, but this is the first official release.

Themes change the look and feel of a phone's interface, including the backgrounds, menus and sometimes the icons too. If you're new to themes, click here to see a step-by-step guide to installing and changing themes on N-Gage-compatible phones.
