So I'm running OS 3.0 on my iPhone 3G. When i try logging into my YouTube account, it says authentication failed. The log in information is correct; I have no problem logging in on my computer. Anyone else having this issue? Suggestions? EDIT: Figured it out. You have to confirm your email address with Youtube before it will allow you to log in on the phone. Didn't see this in any literature, but good to know.
