Specifically, I'm on an AT&T mobile share plan and I'm not the primary account holder. Will I need the primary account holder's AT&T username/password/passcode/social in order to buy a phone through the iPhone Upgrade Program as a first time enrollee? I understand a credit check will be run and I'll need to provide my own credit card and social for that part, but I'm specifically asking for the sake of buying the AT&T version of the phone to add to the current plan I'm on. Thanks to anyone who has any info on this, I've been trying to contact Apple through chat and it's been a long wait so far.
