Apple have released a new advert to demonstrate its Siri application for the iPhone 4S.

The advert features Father Christmas (or Santa Claus) using his iPhone 4S to find a location where he needs to deliver presents, to check the weather and to receive a message from Mrs Claus.

We just hope that Santa hasn't taken an iPhone meant for someone else, otherwise we could have one very disappointed child !

We're also concerned that the iPhone's GPS might not work so well at the altitude Santa's sleigh reaches. We also wonder whether Santa's navigation software comes with a special flying mode, otherwise Santa he'll unnecessarily be following the road outlines !

The guys at 3G are currently working on hacking Santa's iPhone 4S's GPS so we can setup an ambush and steal everybody's presents. So if no presents arrive under your tree you can blame Apple's iPhone software developers !
