I am writing my cover letter for apple creative job. Who should I title it to? Dear...?

Start here: http://www.apple.com/contact/ - click the icon at bottom right to change country if necessary. The 'Apple Corporate' numbers would presumably be able to advise you who to write to.

If you are applying for a specific position from the Apple web site, it will usually list the name of the hiring manger. You can address it to him. If you are not applying for a specific position, Roger has it right, contact Apple Corporate.

And, in addition, I would suggest writing proper English and not using wrds like "wanna".
