Apple’s special event replay for their September iPhone event is now available on the company’s website. Just head to the event page and it will start streaming.
Again, here are the streaming requirements according to Apple:
Streaming video requires an iPhone, iPad, or iPod touch with Safari on iOS 9.0 or later, a Mac with Safari on OS X v10.11 or later, or a PC with Windows 7, 8, or 10. Windows 10 also requires Microsoft Edge. Streaming via Apple TV requires an Apple TV (2nd or 3rd generation) with software 6.2 or later or an Apple TV (4th generation).
The replay will eventually make its way into iTunes for download, and on YouTube soon.
