The free service will initially be available on the Xbox Live Arcade, Microsoft’s paid-for access to Xbox Live Arcade games

The online service will initially be available in beta form with the Xbox Live Gold Preview Program, which will last until March 31. Gamertags will be supported up to ten personal profiles, including Gamertag Leaderboards. Gamertags will be used to enhance a community profile’s visibility in the Xbox Live Marketplace. Users will be able to view their Gamertag on “any profile that has been pinned to the Dashboard”, so users can see what’s up, view their Gamertag, friends lists and more. Status updates will also be available via the Dashboard. Status updates will be grouped into three categories: General Updates, Content Updates, and Developer Updates. The former is the “first and last updates of the group that are currently available to the public”, the latter is the “last updates of the group that are currently available to the public.” The third category is “Next Release – Expect more features and updates in the coming months.” While not providing any details, Microsoft says it will let developers know when their apps cannot be updated because it “will give more information about that release to the developers.” However, it has not yet confirmed any plans to release the update list and release schedule. The free service will initially be available on the Xbox Live Arcade, Microsoft’s paid-for access to Xbox Live Arcade games. Microsoft is also offering a one month trial deal with the Xbox Live Gold subscription for Xbox 360 SmartGlass. The package includes the Xbox 360 SmartGlass and the “Xbox Live dashboard” as well as a “digital game card” for access to the Xbox Live Marketplace. The Xbox 360 SmartGlass is expected to launch in September, just over two months after it launches.
