According to the NewYork Times, a person with direct knowledge of the iPhone 4's design indicated that the device's reception troubles will be fixed by a second software update, different from the iOS 4.0.1 update released today. The same source indicated that a recall was not in the works.
This person said Thursday that ..,
the iPhone 4 exposed a longstanding weakness in the basic communications software inside Apple‚Äôs phones and that the reception problems were not caused by an isolated hardware flaw.
Instead, the problems emerged in the complex interaction between specialized communications software and the antenna, said the person, who agreed to speak on the condition of anonymity because he was not authorized to discuss the matter.
The glitch could presumably be fixed with a software update, and it appears to be unrelated to one that affected the display of the phone's signal strength.
This same source went on to say that the problems were longstanding but had been exposed by the design of the iPhone 4. All cellphones can be affected by the way a hand grips the phone, but well-designed communications software compensates for external factors and prevents calls from dropping.
