The big question floating around the Webnets today is that AT&T will charge $55 for an iPhone Internet tethering plan. What’s not clear is if this $55 will include the $30 iPhone data plan. If so, it’s not a bad deal. But if AT&T is trying to tack on an additional 55 bucks to customer’s already high bills, that just isn’t going to fly with most people. Either way, those of you who haven’t hacked your iPhone to support tethering will have to wait until the end of summer to find out.
