In use it's all a bit basic compared to the competition, but hey, it's early days and the more Twitter clients the merrier! Here's a brief walkthrough:
Fenice for Twitter is commercial software, but there's a 24 hour trial version, so you can take it for a spin.
Note that there's no background agent on Windows Phone, so there's a short wait each time you go back into Fenice, while new tweets are gathered. I'll add Fenice into my main comparison feature once it's had a few more updates and is mature.
