Apple antenna issue a 'physics problem,' not a software problem

Almost a week after the iPhone 4's launch, questions remain over why users experience signal loss when gripping the phone in a particular way.

Apple has called this a "non issue," despite users being able to repeatedly reproduce the problem. In the meantime, it's been suggested that it might be a problem that can be fixed with a software update. Others have said, and Apple has suggested, that users buy a case to prevent fingers from coming in direct contact with the antennas built into the metal band surrounding the iPhone 4.

The antenna being built into the iPhone 4's exterior casing is the reason for signal loss, and can't be fixed with a software update, Anandtech reports.

Brian Klug and Anand Shimpi at tech blog Anandtech have conducted their own hands-on experiments comparing different smartphones and their reception when the antennas are covered. They sum up their findings this way: "At the end of the day, Apple should add an insulative coating to the stainless steel band, or subsidize bumper cases. It's that simple."
