By visiting Ug Apps you can get all the information on the current Windows Phone apps that are available for download.
After the release of Windows Phones I upgraded to one of the first release hardware models and also got a developer license. I then decided to make use of this license and start developing. I taught myself C# through the purchase of some books and many nights spend on the Internet searching tutorials and trials.
Further information on the apps already released can be found on the side links or at apps.pebsi.co.uk
