Makes you wonder how AT&T calculated that 98% of its users stayed within 2GB of data per month. If you download more than 65MB per day in a 31 day month, you'll be over your allotment. 65MB isn't all that much if you think about it. A few emails with attachments or in html format, some light youtube, music streaming and surfing each day will definitely put you over the new AT&T limit.
