today I upgraded to iOS 6. I wanted to get my caller ID synced from my phone to my iMac, so I logged out from my apple id in iMessage and Facetime and now I can't login again. I get this message: "The user name or password for "firstname.lastname@example.org" was inorrect. Try again." I'm sure that I'm entering the right Apple ID and password. It's only not working for iMessage and FaceTime. I was able to login using the same ID into App store and iCloud. I tried to even erase every thing on my iPhone and iPad and restore to original settings and still no luck. Help please.
