What is the pressure contact under the back panel for?
Everyone's heard about (or experienced) the RF signal attenuation that occurs with the new iPhone 4, but how exactly is the stainless steel band attached to the internal circuits to be used as the antenna. Most interestingly, I was reading through the iPhone 4 Battery Repair Guide on the site and noticed that Step 6 refers to the pressure contact as being part of the antenna system! Is this true? Is there more to the antenna system behind the glass panel on the back? I'd investigate myself, but I don't want to risk ruining my new iPhone 4 :( I was hoping someone could post a teardown of the antenna system just so we could all get a better understanding of how it works.
