T-Mobile customers with a Sidekick or Sidekick 3 will be able to subscribe to the service for $3.99 a month, which gives them access to a library of 150,000 music and radio programs including shows from NPR, MSNBC and CNN.

Mobilcast is already available to Alltel, AT&T and SunCom customers in the U.S.
