Sheathing something as slick and pocketable as the iPhone in a holster feels wrong to me for many reasons, but this particular holster adds the handy ability to charge your drained batteries with its own rechargeable Li-ion battery back. It’s good for one full charge before it needs to be recharged itself. Handy, and at US$25 the price is right, but this thing is huge. Product page says this only works with first-gen iPhones and iPod touch–but I don’t see any reason why you couldn’t squeeze a 3G in. [Product Page via BBG]
