However, to post holiday photos you will need to use Earthscape [iTunes link] to upload it. Then, make sure you choose to put it in Santa Tracker.
It has a nice banner going across the top of the app telling you how much time there is until Christmas.
And it has the same controls as Earthscape. To view the landscape in 3-D, you have to do a two-ringer drag on the screen. Double taps zoom in; pinch-out zooms out; and a one-finger drag across the screen moves the map in that directon. The crosshairs at the bottom of the screen gives you your current location.
Finally, the sleigh icon shows you where Santa will be on Christmas Eve according to your current time. Very cute.
It's FREE in the App Store.
