Here's what Apple's headquarters looks like ahead of tonight's iPhone event.

Apple has decorated the entrance to 4 Infinite Loop with a banner that sports the same design as the invitation sent out to media for the event last week. Four colourful flags are positioned outside the entrance, too.

In its invitation, Apple promised to "brighten everyone's day" with the event, which we expect could be a hint that the rumoured iPhone 5C will come in multiple colours, hence the colourful banner, flags and invite.

Apple's event will kick off at 6pm BST at the Town Hall at its Cupertino headquarters, and is expected to see the unveiling of the iPhone 5S, iPhone 5C and more. We should also learn more about iOS 7, OS X Mavericks and the new Mac Pro, all of which were previewed at WWDC in June.

We'll be covering the event live here at Macworld.co.uk, so tune in this evening for up-to-the-minute news, photos and reactions.
