If you're tired of the standard keyboard on your iPhone check out this MacBook Air-like keyboard for the iPhone. It's just a mod that changes the look of your keyboard. It does not change the functionality in any way.

If you want to add this mod to your phone you'll need a jailbroken iPhone. You'll also need to uninstall any other customized keyboards you have. The MacBook Air Keyboard app is already available from Installer.app, via the Planet-iPhones source, which is part of Community Sources now.
