Around three years ago I bought one of the first models of WP7 phones to appear - HTC Mozart 7 - which was very similar to the Android-based Nexus One. Wanted to see what's like to be an early adopter and early player in the app marketplace. I managed to get a free app registered on the app store: Fast Offline Translator EN-DE. http://www.windowsphone.com/en-us/store/app/fast-translator/ccf24cce-d48e-e011-986b-78e7d1fa76f8 I did it mostly for myself as I knew very little German. Not much has changed since. This is the story of doing the development, deployment and update for that app.
Electronics and programming interspersed at various levels of difficulty.
