Most iPhone cases simply protect your phone without thinking of style or multi-functionality; however the BookBook case for iPhone 4 and iPhone 4S has mulit-functionality at its heart, by being an iPhone case and card wallet all rolled into one.

Available now at Mobile Fun, the BookBook case is designed to look like a luxury, vintage, leather bound book.  It has a wallet on the left when opened and a phone holder on the right.  This means that when you pop to the shops, simply take the BookBook with you and your pockets are a lot lighter.

The wallet section has a really convenient ID window, meaning that you don't have to fumble in your pockets for your ID - it's easy to access and view, making life that little bit simpler.

When your iPhone is in the BookBook case it's still fully functional - eaning you can still access the charging port, headphone jack, home button and volem.  The case also doesn't cover the screen, so you can use all of the touchscreen either portrait or landscape to full advantage.  When taking calls the spine of the BookBook can be folded back, so calls are comfortable to take and offer that piece of mind knowing that your phone is protected at all times.

If you want to take a photo while your iPhone is in the BookBook, simply pull the quick tab and your iPhone slides up a quarter of an inch to expose the lens, meaning you can capture the moment in style and without having to remove your phone from the case, so it's one of the perfect cases for iPhone for those who want protection and style in one handy package.

The BookBook case doesn't add much bulk to your iPhone yet provides the perfect disguise and cover for your handset.

It's avaiable now from Mobile Fun costing £54.95, along with a large Kindle sleeve range.
