If I buy an iPhone 4, am I going to have big radio frequency reception problems?
It depends on how you define “big” and on a whole bunch of other variables, such as what 3G frequency you’re on, maybe your body mass index and even whether your hands are sweaty. There have been a rash of complaints from new iPhone 4 users that when they wrap their hand around the phone to take or make a call the phone’s signal strength indicator — those bars on the screen — can show a big drop.
