Want to have a party in your pocket? It may not be the best of taglines, but that’s exactly what they’ve decided to use for the iBottleopener. We’ve all been in the situation where we can’t find a suitable bottle opener in a pinch, but we always have our smartphones close at hand.

With this in mind, the iBottleopener can really help you under such circumstances. It is a protective case that’ll fit the Apple iPhone 3G and iPhone 3GS, but it also comes with a built-in bottle opener. This certainly makes it one of the more unique products we’ve seen, as other iPhone cases may include additional battery life or some other “useful” function. Then again, bottle opening can be pretty useful.

The product is currently patent pending, but the developers are looking to get about $20 for each case, plus four dollars for shipping. The current version will only work with the iPhone 3G and 3GS models, but a iPhone 4 iBottleopener is also in the works.

If you were to develop a new case for the iPhone (or any other smartphone for that matter), what innovative feature would you choose to include to separate your product from the rest of the crowd? A corkscrew? A nail clipper? A screwdriver?
