This wouldn't be notable except that the redesigned iPhone has something of an antenna problem. Holding the phone a certain way can cause the signal to fade or cut out.
Apple isn't saying whether these are new openings or spots that were recently vacated. But the company is looking for experts with at least five years of antenna design experience, Apple prefers someone with a PhD and the person "must have strong problem solving skills and strong working knowledge of radiation performance. Antenna and wave propagation theoretical background is essential."
A master problem solver could be helpful considering a lawyer is working on a class action lawsuit against Apple because of the new iPhone's antenna problems.
Apple's public answer to the problem felt flip -- buy a protective case, or, in a widely reposted e-mail attributed to CEO Steve Jobs, "Just avoid holding it in that way" -- the hunt for experts indicates a real fix could be underway.
