I for one, have no idea why I've racked up 90mb in the past two days, with no audio or video streaming. I go on maybe 30 webpages a day, get 5 emails a day, twitter and facebook often, as well as the occasional data using app. I shouldn't have this much data. I'm also using onavo, which compresses data. So what do you guys use your data on? I need to track down what is causing this issue.
