We at ZDNet UK have done some deep investigation, and it turns out those $10/MB prices are derived from costs that are more like 3c/MB. In other words, you're paying a ridiculous amount for something that costs next to nothing to provide. Consumers, businesses, app developers — everyone is getting screwed here.This has to stop — please sign our petition."
