Error message when I sign into itunes on my iphone

[None Such]

When I try to update the apps on my iPhone I'm getting this message:

"The Apple ID you entered couldn't be found or your password was incorrect. Please try again." My apple ID and password are correct. Has anyone else had this problem? How do I fix this?

Side note; my wife was having this problem with her iPad last night and after I updated it, it was fine. I updated my iPhone and no such luck.

Thanks.
