If you’d like your iPhone to look a little more upscale, why not dress it up in a little leather? Just swap out the glass back with this gorgeous, hand-made leather back from Sled, and your iPhone will be ready for a night on the town.

Sled’s Pack is available in Ink, Natural, and Cognac leathers, as well as in hardwood and waxed canvas, and it’s available for either the iPhone 4 or 4S. Each back is made-to-order, and special features, such as initials, logos, and artwork stamping, can be added upon request. It’ll cost you a pretty penny, though, to make your iPhone this handsome. The Pack carries a hefty price tag of $110.

As a nice little bonus, the Pack back includes an elastic strap that will hold your credit cards and cash for when you want to leave your wallet at home. A couple of weeks ago we wrote about the Elasty iPhone case, which includes a similar feature. Since the Elasty case is just a concept right now, it’s nice to see a similar wallet alternative that is actually available for purchase.

You can pick up the Pack directly from Sled.
