A revelation from Apple has shed light on the iPhone reception issues that have once again come to the forefront with the launch of the iPhone 4. Apple recently admitted that iPhones have been inflating signal strengths and masking poor reception in a flaw that goes back to the first iPhone models.

“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,” Apple said to its iPhone users Friday.

Many cases saw the iPhones display two more bars than they should have, meaning the signal strength of dropped calls wasn’t strong to begin with.

“I’m still in awe that it took them four generations [of iPhones] to figure this out,” said Tina Teng, analyst at ISuppli Corp. “They’re not giving consumers a satisfactory answer. It still goes back to how you hold it.”
