Following today’s press conference over at Cupertino’s campus, Apple has just launched a new webpage: apple.com/antenna where they explain all the details regarding the signal degradation issues people have been recently reporting.

“The opposite of amplification, attenuation happens whenever a signal is obstructed. All antennas — including television, radio, GPS, and cellular antennas — can experience attenuation. And with most antennas, the density and composition of the human hand can cause attenuation to a greater degree than some other materials. On a mobile phone, signal loss typically occurs when your hand attenuates the most sensitive part of the antenna. In the photos and videos below, we demonstrate how different grips cause attenuation on many popular smartphones — including iPhone 4 and iPhone 3GS.”

The webpage shows the signal attenuation problem across 5 smartphones: iPhone 4, iPhone 3GS, Blackberry Bold 9700, HTC Droid Eris and Samsung Omnia II. There are technical details and videos for each phone.

Well played, Apple.
