T-Mobile wants you to have a cheerful holiday season. How do we know? Because they just kicked off a new Unlimited Cheer campaign which sees them giving away Galaxy Note II’s and Galaxy S IIIs, that’s how.

This holiday season, T-Mobile will embark on a nationwide journey dashing across the U.S. from Seattle to Chicago to New York and more to give ‘Unlimited Cheer’ to some lucky fans.

Starting today (December 5) and running until December 20, T-Mobile is going to host holiday parties that will also give folks a chance to meet professional athletes. You’ll want to follow T-Mobile on their social network channels as that’s how you’ll know where you need to be.

If you’re the first person to arrive and check-in with Foursquare then you’ll net yourself a new Galaxy Note II with a full year of service and a MOGA gaming system. The next three people to check in will win a Samsung Galaxy S III, a $50 gift card, and the MOGA controller. For all other check-ins, you will earn 30% off an accessory at a T-Mobile store.

Fans unable to join the “Unlimited Cheer” events in-person also have a chance to win a Samsung Galaxy Note II or other great prizes simply by visiting T-Mobile’s Facebook page and taking a “Naughty or Nice” poll.
