Are you sure it actually downloaded that much? The download meter on mine (or whatever it's called) scared me when I saw it showing 8GB to be downloaded. I was relieved to see that it started at 7.5GB, so it's only downloading about 500MB.
Perhaps they're using the same algorithm Apple used to calculate the signal strength on the iPhone.
