Hmm...did a little math and that would mean you sustained an average download speed of about 5 mbps for 2 hours. IDK how Bell is with their speeds but where I live, I can't get above about 2.5 mbps on at&t. But even if the speed is possible, not sure what it could download for 4Gig. It usually only downloads headlines and a thumbnail sized picture.
That being said, I stopped using Pulse after about a week when I found it was using a LOT of battery in the background. I prefer a more basic RSS reader that is more efficient, even if its not as pretty.
