Hi, I just got a notification that I've used 2 GB of 4G data today, and I don't see how this is possible. The phone is reporting that virtually all of the usage is through tethering, and yes, I've had the computer tethered today. However, I've only been using OneNote and I can't imagine that it'd possibly use anywhere near that much data. Activity Monitor only seems to show usage since you launched the app. Is there some way I can find historical usage?
