My JetPack was supposed to have used about 4 GB Sunday, 8/2. I visited the sites I usually visit each day, and over the course of a year I have averaged less than 0.25 GB used per day.This increase was a shock, and I am wondering if this is a glitch anyone else has experienced. I use a laptop, run no apps or video and do not stream audio. I use Flash Blocker, which helps reduce the gigabytes I use.
