Lovely translation of “Letter from Apple Regarding iPhone 4″ by John Gruber:
Apple: “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.”
Translation: “We decided from the outset to set the formula for our bars-of-signal strength indicator to make the iPhone look good — to make it look as if it ‘gets more bars’. That decision has now bitten us on our ass.”
