The broadly reported reception issues with the iPhone 4 can all be traced back to the way iOS reports signal, Apple now claims. "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," part of a new PR statement reads. "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."
