Apple’s latest response to the iPhone 4 antenna issue:

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.

Apple will soon be releasing a software update that will fix the problem by lowering the number of bars displayed on your phone.  In related news, in response to my students’ grade groveling I have re-examined the midterm and noticed that everyone’s score was 5 points higher than it should have been.  The curve has been re-calculated.
