T-Mobile confirms gratis WiFi calling for the magenta-clad masses

Last week, the online grapevine foretold that T-Mobile users would have complimentary calling over WiFi. Now, the pink provider's powers that be have made good on the gossip and officially made free WiFi calling official. The service is available to those with Android handsets with the carrier's Smart Wi-Fi app preinstalled and are on T-Mo's Even More or Even More Plus plans. All others wanting a dose of free will have to pony up for a new plan -- you didn't think it was actually free, did you?
