(Los Angeles Times) Apple Inc. said Friday that it was "stunned" to find that its iPhones use a "completely wrong" formula to show how many bars of signal strength they are getting.
Apple said that's the reason behind widespread complaints from users that the latest model, iPhone 4, shows a big drop in signal strength when held in a way that inadvertently blocks the antenna at the bottom of the phone.
That drop seems exaggerated because the phone can wrongly display four or five bars of signal strength when it shouldn't, Apple said.
