Re: iPhone Data Usage Counter DIFFERENT from AT&T (*3282#, *DATA#)

I reset my iPhone Cellular Network Data Counter (Reset Statistics) at the same time my "new month" started. I inentionally synchronized this carefully. I have noticed as I have tracked my usage via the iPhone 4S internal counter (Settings / General / Cellular Usage / Cellular Network Data), and adding the Sent and Received amounts, that what the iPhone is counting is less than what AT&T is counting and reporting back to me via *DATA#. My iPhone 4S thinks it used about 7% less than AT&T is telling me I used. The numbers have continued to diverge, with the iPhone reporting a lower number (yes, I am adding sent and received) than AT&T. Any reasons for this ?
During the month, what is reported on ATT's site is only an estimate of usage and is not comparable to the iPhone counter. To take this further, I have not seen any reports or validation that the counter on the iPhone is accurate/inaccurate? At best/worst it is an estimate of usage.
I would also remind you that ATT will round the days usage to the nearest MB where the internal counter of the iPhone is not rounding in sync with your ATT account. For example, 12.7mb would be rounded to 13mb on ATT but would be counted at 12.7mb on the iPhone.
