Following the press conference and Q&A on the iPhone 4’s antenna issues, Apple has posted a streaming video of the conference on its website. While the video lacks the Q&A session, it does include the presentation that was delivered by CEO, Steve Jobs.

Along with the streaming video, Apple also posted an antenna performance page that shows the loss of signal when various phones, including Apple’s are held in particular ways. Note that the iPhone 4 and the iPhone 3GS, are shown to be running the latest 4.0.1 version of the iOS software, which was released on Thursday.

The three smart phones featured are the Blackberry Bold 9700, the HTC Droid Eris and the Samsung Omnia 2, all of which were released in November 2009. The BlackBerry is available on AT&T and T-Mobile, while the latter two are Android and Windows mobile phones, exclusive to Verizon. The report published by Apple shows that these phones could lose between three and four bars when held near the area that covers the antenna. In comparison the iPhone 3GS and the iPhone 4, lost only two bars.

The new section on Apple’s website is dedicated to the company’s testing facilities, which include 17 different anechoic chambers to test a variety of conditions that could affect wireless performance.

In addition to tests conducted in labs, the iPhone 4 was also subjected to various tests across the U.S. and around the world. Some of the testing scenarios included dense urban areas, motion at different speeds and across low and high coverage areas. Apple stated that it tested the iPhone in every possible scenario, paying particular attention to factors including the call quality, dropped-call performance, call origination and termination.

Apple also repeated the claim that it had invested $ 100 million and thousands of testing hours to make the finest products possible. The new section offers a very rare peek into Cupertino’s labs.
