Just guessing here, but I could imagine that the first run of the 4 has ended or is near completion, and that they could pause production at some point soon and begin to implement a change in the antenna design, be it a coating or what have you. Do you think that someone who orders a 4 going forward from today will receive a phone that reflects a hardware tweak? If not this month, next month...? If that is the case, I imagine it would only fuel the fire for the inevitable class action suit(s), especially if Apple remains silent and/or continues to deny the issue. The People: "The phone is inherently flawed. We demand retribution." Apple: "The phone is perfectly normal." The People: "Then why do phones manufactured in July have an added polymer coating around the antennae?" Apple: "Umm. Just because?"
