An international data plan is not a surprise, but what is itunes radio? That sounds like a cool new feature!
Update: AT&T’s site also shows an interesting and possibly telling quote: “While using data on iPhone is free within the U.S., Puerto Rico, and the U.S. Virgin Islands, International data roaming can get expensive quickly. Consider that just 20 minutes of iTunes radio takes 20MB of data. That’s why AT&T has created two iPhone International packages with more reasonable rates in 29 countries.” (Emphasis ours.) So, iTunes radio, eh? Certainly AT&T isn’t talking about downloading tracks over the iTunes WiFi store — that’s only possible via WiFi. Maybe we have something here.
