This is strange... Last night my wife was trying to update her cached stations on slacker radio and although connected to wifi slacker gave a notification that the data would be downloaded over 3g and an unlimited plan was recomended. The strange thing is I had full strength connection to wifi but the 3g icon was still there and and the red and green arrows were showing data transfer over 3g. When connected to wifi on my captivate the 3g icon disappears. A simple power down fixed the problem and wifi was present and no 3g icon in the status bar. Any thoughts?
