There's nothing worse than being in a beer garden or at a house party, reaching for an ice cold bottle and finding you don't have a bottle opener so you have no choice but to use your teeth, 'OUCH!'. We don't recommend this, unless you're a cowboy, so the iOpener Case and Bottle Opener for iPhone will be just the thing for you.

The bottle opener comes with a free app that automatically launches when you open your beverage. The app asks you to select your drink from a list of over 1200 drinks and it will make a note of it and your location. The time will also be recorded so you can post it on various social networking sites allowing your friends to keep track of what you're drinking, and for you to see what caused that massive hangover the next day.

The case is made from polycarbonate plastic which means it is lightweight but strong enough to tolerate constant bottle opening. The bottle opener stays neatly in the case when not being used so it isn't always on show. (Jemma Stockton)
