So I just called ATT to change over to the 4gb mobile share plan. I used to have 700 minutes, unlimited M2AM, unlimited text, 3gb on mine phone 250 meg on wifes phone. around 145 bucks a month after my 20% fan discount. After talking to att, and confirming with the email I recieved I am now Paying 56 (70 - 20%) for the base 4gb plan, and 40 for an additional phone. I guess the first $70 plan includes one phone, and then you pay for the extra. I was under the assumption that it was 70, plus 40 for each phone. So now I'm paying $96 a month and get more data plus teathering seems a bit too good to be true!
