Differences in Data Usage Meter and AT&T Meters

I have an iPhone 4s from AT&T with the 2GB/month plan. I noticed that the Data Usage pane in Settings says I've used less data than when I check with AT&T using their website. Is there anyway to explain this?

remember AT&T side it is lagging a few days so stuff at the end of last month could easily be on this months. Also the one on your phone does not always have all the extra overhead on it so it will be a little out of line.

I've never had all that great of luck with phone based data usage monitors on android. I wouldn't be surprised if iOS is slightly inaccurate too.
