This morning I found out that my first Windows Phone 7 application had passed testing. It's status is now "Published to Marketplace", but I have not been able to see it appear on my phone yet. Hope it does so soon.
In the meantime, here are a couple of screenshots of the application in English; it supports English, German, Spanish and, even though not supported yet, Dutch. All the content that is shown (RSS feed items from my companies website and its tweets) is in Dutch only, however.
