Why would anyone want to do so? The change would only save you $5 per month and would give you a limit of 500 MB instead of 6 GB. For only $60 more per year you get a 12X greater data transfer limit. I can't even fill up my car for $60.Any clue if people who have the $30/6gb plan can sign up for one of the new ones without any penalty? I doubt it...
