GameKit / GameCenter - I386

I'm having some hard time with the iOS GameCenter I'm following some tutorials on youtube but as soon as I finish the code I get this error:

It looks like you haven't added the GameKit framework to your project.

If your using Xcode 3.2.x:

• Right click the Frameworks group/folder in the file tree (on the left of the xcode window)
• Press Add, and then select Existing Frameworks...
• Scroll to GameKit.framework and double click it

If your using Xcode 4:

• In the file tree, click on the project (the item at the top)
• Select your target
• Go to the Build Phases tab on the main panel
• Expand the Link Binary with Libraries
• Press the + button
• Scroll to the GameKit.framework and double click it.

Did you add the GameKit.framework to your project?
