If you like the idea of looking at your iPhone’s innards while using it, you should download these new wallpapers that are perfectly-sized images of the internals of the iPhone 5s and the iPhone 5c.
The folks at iFixit are one of the best teardown experts out there, so it’s no surprise these wallpapers come from them. They’ve taken care of sizing the wallpapers so they work well with iOS 7′s home screen parallax effect too.
To set any of these photos as your wallpaper, open this page on your iPhone, long press the photo, save it to your Camera Roll, and navigate to Settings > Wallpapers & Brightness to select the image you saved. Alternatively, you could tap on the direct links below to save the image to your device.
