With Windows Phone 8, apps will be available for download from Marketplace in more than 180 countries and regions—roughly three times what we serve today! Developers in these markets can also submit apps via AppHub, up from 38 markets today. See Todd’s post for a full list.
For a limited time only, when register at YallaApps today, you will be able to migrate to App Hub for free when it is available. No $99 roadblock!
