Hello, I have a ? When you upgrade to 2.3.4 on Atrix you get a new music player ( which is great ) but you get internet radio also whit all kinds of stations. What I want to know is when you play them without wifi does AT&T charge you for data useage? My daughter has a Samsung Android phone with a radio on hers and she don't have to pay data useage I was just wondering since it's on the music app now. Thanks
