Elvis Presley? There’s an official iPhone app for that.

iPhone developer USAopoly is hoping that Elvis Presley will prove to be The King of Apple's App Store, having released an officially-licensed game called The Official Elvis Challenge.Selling for $4.99, it's a trivia game offering more than 2,500 questions split between different mini-games, covering Presley's entire life. The deal with Elvis Presley Enterprises means that more than 200 photos of the star are included in the game too.Music? The game makes use of something we've seen before: integration with the iPod music library, so that players who already have Elvis songs and albums on their iPhone or iPod touch can have them playing in the background.The Presley estate is also keen to stress the authority of the game's information:”Whenever possible, facts were derived from contemporaneous documentary evidence as opposed to people’s memories, which are not always reliable. This means that some of the questions and answers will be in conflict with myths and misinformation that have long been part of Elvis lore.”Fans of The King will love it.
