This looks like a really cute app, and if you're looking for that one phone call from Santa that doesn't cost anything, this may be it.
It looks like it might be quite large - I am going to have to clear some space on my phone before I can install it, but it looks to be rather worth it.
You can watch a video on the website of the call. You can also choose the date and time of the call, and a 'unique' Santa message. You upload a photo of your child too, so that their picture appears on the screen during the call and Santa will mention their age, country and so on.
