It was the other way around: Apple fixed the reception indicator to reflect coverage more accurately. “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. [...] To fix this, we are adopting AT&T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area. We are also making bars 1, 2 and 3 a bit taller so they will be easier to see. We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.” http://www.apple.com/pr/library/2010/07/02Letter-from-Apple-Regarding-iPhone-4.html http://www.apple.com/pr/library/2010/07/02Letter-from-Apple-...
