We know iPhone tethering has been "Coming Soon" officially from AT&T for quite a while now. We already pay $30/month for unlimited iPhone data. And now we're being asking to pay $30/month for unlimited iPad data. $30 + $30 = $60 (duh) So maybe they offer a small incentive on an unlimited tethering plan? Say $50 or $55/month? What do you guys think? [Yes, I know about tethering via jailbreak + MyWi or the like. Just trying to focus here on speculation about AT&T's plans].
