If you got a confimation e-mail, you DID get a straight answer from AT&T. Why are all you people letting your blood pressure go up like this? AT&T said they are shipping it overnight so it arrives as early as Friday. That means there is NO REASON for them to give you shipping information before they actually ship it. If they did, all you would see are threads of people complaining their package hasn't left the factory yet.
If they ship it priority overnight tomorrow, then you will get the tracking number tomorrow.
I honestly think they did it with the intention of people buying more phones from them versus Apple. Apple promised us the phone on the 19th. ATT knew they couldn't get ALL of them to customers on the 19th....so what do they do?
Use some deceptive marketing. "As early as" the 19th. Sure, we all know it means that it could get here later than the 19th....but they wanted to make it look like Apple's statement so more people would buy phones directly from them.
That's what I think.
