Not true at all. I really wish people wouldn't post things without knowing what they're talking about. Each retailer (carrier) had a designated number of phones available for sale. That should be apparent based on the fact that all 3 U.S. carriers and Apple have been providing different shipping ETAs throughout the day once the stock of the 16GB model started to dry up. Some carriers ran out of their allotment faster than others.
Yes. And the fact that Sprint is sold out of the 16gb models pretty much confirms this.
