Good morning! Windows Phone Radio 21 went live late last night here in the Pacific time zone, and we have a couple great guests on the show this week. First, Eric Hautala sat down with me and Greg Sullivan to talk about his recent post on the upcoming update. Later in the show, Megan West from the Zune Marketplace team drops in to talk about SXSW in Austin, TX and calls out some of the bands and music to keep an eye and ear out for. We featured a couple apps this week including Bubble Birds and Local Concerts. Download in Zune Marketplace, iTunes or from the Web here.
