Update: You can now watch the keynote video on Apple's site at http://www.apple.com/apple-events/september-2013/

Alternatively, read our coverage of what happened at the Apple Event

Here, we advise you on the best way to keep up with the new iPhone 5S and iPhone 5C launch.

Although it's not been officially announced yet, it's quite possible that Apple will live stream its special event on its website, as well as on the Apple TV (we'll update this story if Apple confirms this). However, it's worth noting that the live stream isn't always the quickest way to find out what's been announced.

At WWDC 2013 in June, we found that Apple's live stream was significantly behind. In fact, in some cases, the whole keynote had actually finished before Tim Cook had even taken to the stage in the stream on Apple's website.

The best way to find out the news as it happens is to actually be at the event, and we've got reporters from Macworld in the audience tonight. They'll be live blogging the event as it happens, and will also be sharing photographs from the event so you can see what's being announced. Plus, we'll also be bringing responses, reactions and opinions about Apple's new products.

To follow our live blog, bookmark our iPhone event live feed page. For an example of what to expect, here's the live feed from last year's iPhone event. You can access our live feed on your iPhone or iPad, too.

Apple has made all of its keynotes dating back to October 2010 available to watch on its events page, so we're sure that tonight's keynote will soon join them when the event is over.

We'll also be tweeting updates and sharing news on Facebook, so follow and like us to stay in the loop.
