Apparently Sprint is pushing out “something big” today, but there has been no hint at just what that “something big” is, but the guys over at gizmodo seem to think they have an idea of what is coming.

The guys believe that Sprint will intro a new calling feature known as “Sprint Any Mobile” which is predicted to deliver unlimited mobile to mobile, meaning your Sprint handset to any other mobile phone with any carrier and at any time.

Now the thing is will “Sprint Any Mobile” be an optional add-on or a replacement to Sprint to Sprint plans? No doubt we’ll know more later.
