Details:

How to Participate: The Contest will take place throughout the day during normal business hours, local time, at select T-Mobile-brand retail locations (i.e., retail locations operating under the T-Mobile name, NOT 3^rd party retailers of T-Mobile products/services) in the Territory. The Contest begins on December 5, 2012 at 12:01 a.m. local Territory time and ends on December 20, 2012 local Territory time (“Contest Period”). The Contest will be available in each city within the Territory on different days during the Contest Period.  

Once per city within the Territory during the Contest Period, “Carly” (the T-Mobile spokeswoman) will check-in on Foursquare and upload a photo of herself at a T-Mobile-brand retail location. Carly’s check-in on Foursquare will be posted on T-Mobile’s Twitter and Facebook pages. You can find T-Mobile’s Facebook and Twitter pages at https://www.facebook.com/TMobile and https://www.facebook.com/TMobilerespectively.

Step 1 – Check-in on Foursquare at the T-Mobile-brand retail location after Carly has checked in to that location.

You must arrive at the T-Mobile-brand retail location Carly checked in to and check-in to the location on Foursquare using the Foursquare application on your mobile device.

Step 2 – Find the Contest Adjudicator.
