iMessage prompting for the wrong email address? FaceTime was no problem...
Trying to set my Dad's iPhone5s with a new AppleID, and while attempting to set him up with iMessage, it's asking for the wrong AppleID address... It's almost like he mistyped it somewhere, but now I don't know how to change it. Whenever I attempt to use AppleID to sign in with iMessage, it just prompts for a password, but won't let me change the e-mail.
I checked with FaceTime, and I WAS able to use the correct AppleID for that... Not sure where it's gone wrong. Any help would be appreciated.
