Here's everything you need to know about today's iPhone 7 launch

After months of anticipation, Apple is set to unveil its long-awaited iPhone 7 at 6pm BST (1pm ET) in San Francisco this afternoon.

Although Apple is notoriously secretive, almost every detail of the new device has already been revealed if a major leak is to be believed.

The new features are expected to include a waterproof design, two new colours, and wireless headphones.

Apple has sent out media invitations for an event at the Bill Graham Civic Auditorium in San Francisco today at 10am local time (6pm BST).

For those without an invitation, Apple will also be live streaming the event on its website for Apple devices, or Windows users can watch on Microsoft's Edge browser.  

The event will not be available on Android devices.

The image on the invitation used is of coloured dots, which could represent new colours available, or may portray water droplets, suggesting the phone will be waterproof.

No headphone jack - The technology firm is said to be bundling 'EarPods' with a Lightning connector, as well as a Lightning to 3.5mm adapter in the box

Airpod headphones - a leading analyst has revealed Apple will also unveil its own wireless headphones, called AirPods, at the event

New colours - A 'dark black' model will replace its Space Grey finish. This will sit alongside the silver, gold and rose gold finishes that have been popular parts of previous line ups

Water resistance - Apple is set to introduce IPX7 water resistance, which already exists on its first Apple Watch model

More powerful chip - The current A9 chip could be replaced with an updated A10 processor made by TSMC, which could run at speeds up to 2.45 GHz

Dual lens camera - A long-rumoured feature, the dual-lens rear camera is said to be coming to the iPhone 7 Plus, but not to the smaller iPhone 7

Redesigned home button - the home button could be overhauled to make it fit flush against the chassis, which is a result of the new water resistant design

Wide colour display - The new iPhone is expected to include the wide colour display technology that was introduced on the iPad Pro

Stereo speakers - The earpiece receiver could be upgraded at the top of the device to work as a speaker

Curved screen - Earlier rumours have suggested that at least one of the new iPhone models will include a curved display.
