... Because of the 3G iPad? It is argued that the iPad was made before the iPhone. Had AT&T allowed tethering from the iPhone, the 3G iPad would be pretty pointless. We got rumored news that the tethering plan for AT&T would be around $30. This happens to be the charge for 3G access unlimited on the iPad. With the fact that we know that apple knew what they were producing well in advance, and the seemingly close ties that they have with AT&T, it is very safe to assume that tethering was left out to sell 3G ipads.
