T-Mobile just dropped off a special video in my inbox with an almost four-minute video from their “Home for the Holiday Surprise” that took place last week at Chicagoland WoodField Mall. To be honest, this is the kind of fun, viral marketing I’d like to see more of from T-Mobile, especially considering their overseas brethren have perfected the art of the flash mob.

I’ve included two more behind the scenes videos from the event below. All three videos are a lot of fun so check them out.
