I wanted a theme like this and I was wondering the iPhones have such themes besides wallpapers are will also decorate the apps and tools.

There's something a little complicated to theme iPhone, but the good news is… Yes, you can theme iPhone. Probably the one you wanted.

How to theme iPhone:
1. Jailbreak your iPhone. After you jailbreak, you should see a new app called "Cydia".
2. Launch Cydia, search for an app inside Cydia called "Winterboard".
3. After you download Winterboard into your iPhone, the phone will reboot.
4. Now launch Winterboard, there, you will find thousands of themes for your iPhone to install. I hope the one you're looking for is in Winterboard.

There's also another similar app to Winterboard and it's called Dreamboard, you could download it and check for your favorite theme inside it.

p.s. If you're using the newest iOS version (like iOS 6.1.3 or above) you should wait for the jaibreaking tools to be released. Otherwise, you're good to go.
