iPhone Tethering Plan For AT&T

iPhone power users have long complained about the lack of tethering, and this time round word has it that the iPhone will be on the receiving end of a tethering plan for AT&T. Something like this will definitely be able to boost the iPhone’s ARPU, assuming it sticks to the rumored $30/5GB plan. If those figures sound familiar, that is because it is similar to what AT&T is currently offering its BlackBerry users. Do you think this rumor holds any water, or is it just another of many speculations to get Apple fanboys all worked up over nothing?
