It seems that T-Mobile has spilled the beans regarding Wi-Fi calling on the product pages for both the new myTouch and the recently added Motorola Defy.
This evidence firmly suggests that Wi-Fi calling is indeed headed for T-Mo, which is similar to Skype calling and can be used on any voice plan.
You can check this out for yourself by visiting both the myTouch Product Page and the Motorola Defy Product Page.
