Does a keylogger or similar exist for the iphone?

On my iPhone 4 I was checking out a website called GameRant in mobile view. While scrolling, a window pops up with the words "Apple Sign-In" on a top bar and on a white page it says "Success"

What does that mean? Does that mean that my iTunes log in information has somehow been acquired when I didn't even type it at that moment? Anyways I changed my password.

Yes they exist, but only on jailbroken iDevices. You saw an ad.

I never jailbroke my iPhone. I have a cousin who has done it to hers. I wonder what was up with that ad?

Just scareware.

Ok, I appear to get this message again. Now that I got a good look at it and did some research. It appears it isn't anything... Dangerous.
