Nokia's N-Gage hardware was a definite failure (Epic, even), but the new N-Gage platform that runs on their high-end smartphones could turn out much better.
The service, which runs a lot like Xbox Live, is now available on their N81 phone for a preview. Nokia is asking for support in testing the service before they open it up all around.
If you've got an N81, why not give it a try. It's got a few game demos and you'll be doing a service to Nokia.
