T-Mobile has just announced at its “Uncarrier 5.0″ event (which apparently double as the Uncarrier 6.0 event) that all streaming music services will now be free to stream on T-Mobile, including iTunes Radio. This also applies to Pandora, iHeartRadio, Slacker Radio, and Spotify.

Any streaming you do will always be done over the company’s fastest available network, and won’t count towards your high-speed data limit.

Customers can visit T-Mobile’s website to request new services to be added to the “music freedom” selection. As streaming services gain votes, they will be added to the program.
