Yesterday we reported that Microsoft was preparing to release an update today for Xbox 360 including Xbox Music, but it was not specified whether this stat includes also other improvements coming with the new dashboard: now comes the official announcement that it is just the update that will add Internet Explorer, voice search on Bing, SmartGlass support and other improvements. As has already been done in the past it is a " rolling update " that, within a week, will be released a little at a time to all users not to overload the server: you may then have to wait several days before you receive it.
