Yes, I was on the 250mb plan for a week, and then heard the wonderful surprise of ATTs switcheroo.
So I then signed up for the Unlimited plan June 6, but it won't start for 3 weeks, when my 30 DAY 250 plan is up on June 28. I'll probably run out of my 250 well before that and just wait til June29 for my Unlimited plan to start.
I could try to start it early, but I'm afraid to mess with it, with all the new rules. Right now it says my Unlimited plan starts on June 29. I'm going with that...for now.
