Here's the iPhone 5 version of the Aired Leather background, aka Perforated Leather. The wallpaper has been scaled up to 640 × 1136 for the new iPhone's higher resolution, and it comes in dark gray and light gray flavors. These are Creative Commons Licensed, so feel free to share these wallpapers, but it would be awesome if you would also link back to this post. Thanks!

Updated both the dark and light versions of the wallpaper to have more appropriately sized details, contrast, etc.
