This was entered into an April Fools day contest. It's a MAGIC TRICK that you can purchase. It is not a downloadable app. It's simple to do for anyone 8 and up. This won't work unless you have the magic trick to make it work!
Tired of hearing about all the cool things the iPhone has / can do? Check this out... and the iPhone CAN'T do it!

Great brand new magic trick and super simple to perform. If you like this, visit http://smartphonecardtrick.com and learn more! This instructable shows you what each of the steps looks like.
