So you are saying they will now go back, for the sake of the 0.55% (Apple's measurement of the number of complaints) of users who experienced problems with the antenna, and admit that:
"The antenna design we came up with the iPhone 4 WAS horribly flawed and what we said at the end of the summer of 2009 is wrong...it IS in fact a problem...that's why we redesigned it." ???
I would argue that Apple admitting their antenna design is flawed would be an even worse PR nightmare. And by redesigning it 'between model refresh years' that's EXACTLY what they would be saying. Without so many words.
Not being an Apple 'fan boy' here, just looking at the issue from a purely PR angle, like you have been. They stand behind the design, found that it works for nearly 99.5%** of their customers, did NOT change it for the Verizon release and now, somehow they will redesign? Amazingly unlikely to me...just because I think they would want to avoid a different PR nightmare...the opposite of yours.
**(that amount may a lot closer to 100% now as that 0.55% number was from last summer when total number of the iPhone 4s were a lot less than is out there today...or you might argue it could be the same IF the 'flaw' were affecting everyone equally across the globe. If anyone has current values, I welcome the data.)
