Every day brings us closer to the iPhone 6, and all signs point to September for the announcement and availability. In fact the specific dates may be narrowing, according to a Chinese source, as reported by Apple Insider. September 19 or 25 are being discussed as potential dates customers could get their hands on the 4.7" device. A 5.5" version is expected to be announced but possibly later this year. Now we are learning that the larger unit may be dubbed the iPhone Air. This is counterintuitive, as the MacBook Air represents the lighter, smaller MacBook compared to the Pro, but the iPad mini vs iPad Air may set a new precedent, with Air representing the handheld device with the largest screen. Perhaps the better naming convention would be to make the 4.7" model the iPhone Air and the 5.5" version the iPhone Pro while keeping the current iPhone 5s as the basic iPhone.
It's possible that Apple will preannounce the device(s) a week or so before availability, to "prime the pump" as they have done before. This could explain the September 19 date. The later date, September 25 could be the availability date. Some observers doubt this, because it's a Thursday, and Apple typically makes their iPhones available on a Friday. I know this because September 20 is my anniversary and that was when the last iPhone 5s was available! However, China is playing an increasingly important role for Apple and they are expected to get the new iPhone on the first day it's available. Since China is a day ahead, it would be Friday, September 26, when it's Thursday, September 25, in Cupertino. One thing is certain; I know what my anniversary present will be!
