"game changing" announcement tomorrow, and right on schedule, the details have come leaking out. Apparently Sprint's $70 rate plan going unlimited, meaning seven Hamiltons will get you endless mobile-to-mobile calling (to any network, not just Sprint), texts, data, and MMS -- stuff you could already get on the Simply Unlimited plan, but the big change at this price point is the unlimited mobile-to-mobile voice, up from 450 minutes in the current plan. Yeah, it's a good deal, but is it a revolutionary deal? We'd say that all depends on whether or not it comes with a free Palm Pixi.
Update: The Any Mobile, Anytime plan is now official.
