To win the money and the phone (or is it the phone and the money?), simply follow the tweets emanating from @TMobile. These will contain clues as to which T-Mobile location in LA has the Elf. Go over to the store and when you find the Elf, tweet "I found the Elf@TMobile #FindTheElf" and you could end up $1,000 richer and with a heck of a new Android phone as well.
As if you needed any motivation with a free Samsung Galaxy S II going to the winner (oh yes, there is the money too), check out the video below of how the contest played out in New York City.
