Oh no, like I have an AT&T account. I just had to reserve a T-Mobile model because they didn't have any AT&T models of the one that I want. So instead of scanning the IMEI number off the back of the phone they'd be able to scan it off an AT&T SIM card, right? And then it magically becomes an AT&T phone I can use on the upgrade program?
Or is it tied to the actual serial number? Because that would suck
right, this is what I'm saying. You reserved a T-Mobile phone (designated as such because it comes installed with a T-Mobile SIM), so you have to have service with T-Mobile to get it on the Upgrade Program.
Basically what "kind" of phone it is is determined either by whose SIM is in the phone, or for CDMA phones, which service the IMEI (or whatever the CDMA version of that is) is whitelisted on.
