I heard that in addition to AT&T throttling wireless bandwidth (I think for unlimited users up to 3GB now, they are charging an over-usage fee of $10 for every 50GB over the first 150GB. Granted, 150GB is a lot. But when I format my hard-drive roughly once per year and re-download all of my service packs, iTunes & associated apps, etc. 150GB can add up fast. Do any of the other service providers (Verizon, Comcast, etc.) do the same thing?
