icloud email is incorrect in my new iphone

The email address was typed in incorrectly when iCloud was set up on my new iphone. Therefore I cannot "verify" the email, and can't log in. I have since set up an Apple ID on my computer with the correct email address. But my iphone won't let me sign into icloud or the app store because it is associated with the incorrect email address. How can I change this incorrect email address in the phone?? Thanks in advance for your help.
