As they have done for most of its events in the past few years, Apple will once again live stream the upcoming iPhone event. The recently-announced event will take place on September 9, beginning at 1 p.m. EDT/10 a.m. PDT.

From Apple's event website:

Join us here on September 9 at 10 a.m. PDT to watch the keynote live.

In a break from previous years, Apple's stream will not be exclusive to Apple devices and browsers. Apple will also stream out to 75 million Windows 10 users using Microsoft's new Edge browser. If you are watching through an Apple device, iPhones and iPads will need to be running iOS 7 or later, while Macs will need to be on OS X 10.8.5 or later with at least Safar 6.0.5. To watch the event on your television, you'll need a second- or third-generation Apple TV.

iMore will be there at the event, so be sure to stay tuned from the latest on Apple's announcements.
