So, Nokia's N-Gage has finally gone live. Actual N-Gage, not the beta First Access application that N81 owners have been playing in recent weeks. The full N-Gage application is now available for the N81, N81 8GB, N95, N95 8GB, and N82 handsets.
Pocket Gamer has posted a 30-step guide showing you how N-Gage works. It assumes you've installed it, which is explained on Nokia's download site.
