I have searched this but havent found a solution or its a different case. My imessages and FaceTime is successfully tied to my phone number, but i just cant add my appleid or any other emails addresses like (@icloud). Keeps saying "the username or password for.....is incorrect". Im trying to sync between my rmbp running 10.8.2 with my ip5 running ios6. My messages in mb already has my gmail and iCloud but no number, and my phone has only my number. I tried restoring multiple times, off imessages /facetime, restart and switch it back on. tried reseting settings and all, tried with wifi, without wifi, and yes i am certain i typed my password and username correctly. i even tried setting my number as an email address , but its just stuck on waiting to verify. any help would be awesome thanks.
