Cupertino, Calif. - Apple today defended the iPhone 4 against those who say the device has problems maintaining a cell signal.
The company said in a letter to customers that the signal strength is not being reduced an inordinate amount when held in a certain manner. Instead the signal strength is dropping the normal amount, however, the formula being used to decipher the signals strength is incorrect.
Apple stated, "Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don't know it because we are erroneously displaying 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place."
To rectify the problem Apple will adopt AT&T's signal formula and install it into iPhones via a software patch in the next few weeks.
Apple is facing at least five class-action lawsuits from disgruntled customers over perceived problems with iPhone 4's wrap-around antenna design.
