Not going to happen. As a matter of fact, Apple went the opposite direction, stating that the antenna issue is insignificant by throwing a bunch of numbers and videos out.If this is true, the Apple acknowledges that the antennae is a significant issue... something that Apple has yet to fess up to.
Independent customer satisfaction surveys and iPhone 4 return rates also indicate that the antenna design is not an issue. This has also been stated by third parties in other countries (e.g., Norway).
Will this antenna episode affect the way that Apple designs phone antennas in the future? Unknown, but there's a possibility it would.
