Finally, it happened. Apple has just issued an official press release about the iPhone 4 “problems”. It turns out, the iPhone 4 comes with a “totally wrong” formula for calculating the signal strength - it displays more bars than it should. The good news is, this will be fixed with a software update soon.
Still, it seems like you’ll have to keep holding the phone without touching “the spot”. If you’re in a low signal area, the reception issues will still happen, but iOS will display the signal drop more accurately.
Check out the full press release below.
