You would think that using a $650 smartphone to open a bottle of Bud would be a bad idea and, well, you would be right. But for those who dare to spill foam all over their iPhone, there’s Opena. The concept is pretty simple: it’s a protective case you slip over your iPhone with a stainless steel bottle opener attached to it. To add even more beer-drinking functionality to your smartphone, take BrewTrackr for a spin to help you remember which bottles you’ve been opening.
