Open a beer with your iPhone

You can purchase apps for your iPhone that do almost anything along with the normal text, getting on the internet, and making a phone call!   Soon, you will be able to buy a hard plastic case with a slide-out bottle opener for your iPhone called "Opena".  They even tested to make sure your phone would be okay in case your friend gets a hold of your beer prior to you and shakes it up and foams over on your phone and in testing everything went fine time and time again.
