Just a statement of the obvious...The orders placed through Apple seem to be "moving" faster than the ones placed directly through AT&T.
It would be logical to see the CSS come FIRST for those orders that came directly through AT&T.
Then again, VERY little of ANY of the happenings the last few days has been logical.
For those (like me) whose upgrade fees were waived, but it still shows on the CSS, I believe that the waiver will show on the first bill. The CSS is essentially a standard template, with a few variations, and while there is normally an upgrade fee, in the end it will not be applied to all accounts.
If it does show up, then it will be easily enough fixed with a phone call. I'm not sweating it.
