Apple says iPhone 4 problem is software based and will issue an upgrade in a few weeks
Apple says that it has incorrectly calculated the number of signal bars that should be on the iPhone 4 at a given time. The Cupertino based firm says that the result is that the phone overestimates by two bars, the actual signal strength. The statement from Apple says that they will adopt a new formula recently suggested by AT&T which will give a more accurate reading. Also, bars 1, 2 and 3 will be made a little bit taller so that they can stand out better. The problem has been part of the iPhone since the first-gen model was launched and thus, the software fix that will be sent out will also be available for the iPhone 3G and 3GS. Still no word on the "death-grip" and Apple still has yet to agree that it had even made a mistake designing the antenna.
