This should come in handy on the second biggest drinking day of the year. Intoxicase is a protective iPhone case that comes with a built-in bottle opener. Totally unnecessary. Totally cool.
The Intoxicase also comes with a mobile app, which knows when you open a bottle with your iPhone (it has a gyroscope sensor, supposedly) and thus will keep track of how many drinks you've had (very helpful on St. Paddy's Day). The app will also help you find and call a taxi. I've tested the bottle opener myself. Bottle caps snap off with ease, due to the stainless steel opener (which is grafted right onto the Poly carb case). Intoxicase costs $35 and can be purchased here. There's also an Intoxicase Plus for $45 (sleeker design). More info at www.intoxicase.com.
