Today my application went live. After a failed submission and 7 more days of waiting for certification, my application is live on the WP7 marketplace.
This application is an RSS reader for the major Greek sport sites. It was a really nice experience seeing this application start from file -> new project and now seeing it on the marketplace.
Here are some screenshots of the application.
If you are interested in sport-related news and/or you can read Greek and have a WP7 give it a try and let me know what you think.
