A 47-minute video of Apple's July 2010 iPhone 4 'antennagate' press conference featuring Steve Jobs, Tim Cook, and Bob Mansfield has surfaced on YouTube after 16 years. The previously unreleased Q&A portion shows the executives addressing concerns about signal loss when holding the device and responding to questions about their personal use of uncased phones. Apple had initially published only the prepared presentation while omitting the question-and-answer session.
