OK, so I finally figured out what has been devouring my data. Podcasts! Even tho a podcast downloads at 65MB if you stream it, it streams at a rate of about 1.5-2.0 MB/s!!! I blasted thru 200MB in a matter of minutes! I decided to test today if that was the problem. So last nite on wifi I downloaded the podcast I was going to listen to today. As a result, I used 10MB total today, as opposed to over 700MB the day before! So, be careful if you are a podcaster! Always download on wifi before using it, because if it detects Wifi it will BURN you!
