We reported a few days ago that T-Mobile, in conjunction with MLB, would be offering a free membership to MLB.TV Premium, their complete live game streaming service, to all T-Mobile subscribers. The promotion (as well as the Major League Baseball season) is now live. Here's what you need to do to sign up.

Start by heading over to this page on your T-Mobile connected phone or tablet. Make sure you are connected to T-Mobile's signal, not WiFi, or else you will get an error message. Once you open the page you will have the option to create a new MLB account, or sign into an existing one. Chose the appropriate option and then follow the steps to complete the sign-up process.

Once you have signed up you are free to use your subscription on any supported device, not just those connected to T-Mobile. Just use the same credentials that you used when redeeming the offer through T-Mobile's offer page. You have until April 10th to sign up, so don't delay! (Insert favorite overused baseball saying.)
