The date has been set for AT&T's Mobile Share plans. On August 23, customers will be able to choose from a new Mobile Share plan, to keep their current plan, or to change to one of AT&T's existing plans. For now, there will be no forcing new customers onto the Share plans, even when upgrading to a new phone. They have six options in total for "data bucket" sizes at 1GB going all the way up to 20GB.
