As ZDNet's Larry Dignan pointed out last year, T-Mobile and BlackBerry had a falling out and eventually T-Mobile stopped offering BlackBerry devices to customers.
President and CEO of T-Mobile, John Legere, stated:
People who love BlackBerry smartphones and want to use one on America's fastest nationwide 4G LTE network now have that choice. Bringing BlackBerry into our device line-up now also stokes Un-carrier 9.0, which is all about bringing the Un-carrier revolution to business.
I continue to use my BlackBerry Passport on T-Mobile and am pleased to see T-Mobile once again offer BlackBerry hardware. Hopefully, we continue to see new BlackBerry smartphones come to T-Mobile, perhaps the Leap will be next.
