The iBottleopener is a two part slider case which can open bottles with the flick of a wrist. This case won’t even block any ports, so you can plug it in without needing to take off the case. Beyond the bottle opener on the back it’s a pretty simple case. It will work for your iPhone 3G/3Gs and it will soon fit the iPhone 4. It will cost you $19.95 (USD) for one of these cases.
