Apple is hard at work on the next update to its iOS 10 mobile operating system.

According to renown leaker Sonny Dickson, the Cupertino company is gearing up to launch the first beta for iOS 10.3 on January 10th 2017.

The codename for the next operating system update is Erie, he claims.

The .3 software updates often mark a mid-cycle software revision from Apple, and as a result, tend to include an exciting new headline feature.

When Apple pushed-out iOS 9.3 in March 2016, it introduced the new Night Shift feature, which modifies the amount of harsh, blue light emitted from your screen throughout the day, to improve the quality of your sleep. And it appears that 2017 will be no different.

According to leaker Sonny Dickson, iOS 10.3 will bundle a new feature, dubbed Theatre Mode.

Many have speculated that Theatre Mode could refer to a system-wide dark mode, like the one shipped in macOS and tvOS.

Based on evidence unearthed in the first beta of iOS 10, it looked like Apple was preparing to offer the new mode alongside the initial launch of the operating system update, back in September.

Mr Dickson told technology blog 9to5Mac that his sources regarding Theatre mode suggest might “very well might be [an] enhanced version of Dark Mode.”

Apple is purportedly pretty keen on this new addition, since it will get its own Control Centre icon.

The new icon will resemble popcorn, according to Mr Dickson.

Whether the new Theatre Mode will also include functionality similar to Do Not Disturb – making it ideal when iPhone users want to quickly check their phone while watching a movie, remains to be seen.

The news comes days after leaked images appeared online, appearing to show a new Jet White colour scheme for the latest iPhone.

Some sources believed the glossy new colour, dubbed Jet White, would make an appearance in time for the holiday shopping rush.

While that deadline came and went, new video footage appears to rumoured the Jet White colour options on the iPhone 7 and larger iPhone 7 Plus.

The video was originally posted by Sonny Dickson, who has a long history of publishing photos of as-yet unreleased products and components.
