I had gotten this last week. Had called last Saturday to cancel my unlimited plan since I was being throttled so badly that I couldn't stream music without pulling my hair out. After telling the lady that I didn't want to listen to her mobile share pitch, I was sent to a supervisor who offered me the 20 for 10 share plan and said she would do it for me on Monday, as that's when the plan would be available. We hung up and sure enough Monday came and I received a text that my plan had changed, was surprised she remembered. May not be unlimited, but throttled unlimited is worthless now and days anyway.
Worse news is the ridiculous $40 per phone charge they will start doing for the higher plans soon, defeats the point of the "free" double data if we end up with another att tax soon after.
