For those of you in the Xbox 360 Dashbaord preview program, some of this stuff is old hat, but for the rest of us, today's launch of a dozen new applications on the Dashboard is all brand new. Beyond the addition of YouTube, FiOS TV, and TMZ (can we give that one back?), Xbox 360 users get access to MSNBC content, iHeartRadio (actual radio!), and a handful of other services starting today.

Though we expected as much, certain services are region-specific and thusly will only be available if you live in said region (Rogers On Demand only exists in Canada, for instance, as it's a Canadian cable provider). Head past the break for the official list, regions and all.
