iOS 10 release date, features and rumours: iOS 10 users no longer allowed to upgrade or downgrade to iOS 10.3.2

20/10/2016:Today, Apple released the fifth iOS 10.1 beta to developers and beta testers. This is the second beta released in one week.

In future, 10.1 for iPhone 7 and iPhone 7 Plus should include a feature called Portrait camera, which applies a DSLR-like special effect over photos. This tool should only work on iPhone 7 and iPhone 7 Plus, as it requires the dual camera system.

This feature was introduced at Apple's keynote this month, but has only been released for developer betas and has not yet been made available to the public.

Apple's iOS 10.1 beta 5 weighs 1.95GB and is one of the largest iPhone 7 and iPhone 7 plus betas released so far. Similarly to the few previous 10.1 betas, the fifth beta does not appear to contain any fixes. However, it should include some considerable changes.

Along with the fifth iOS 10.1 beta, Apple also released the fifth macOS Sierra 12.1 beta.

20/09/2016:Since iOS 10 was launched, enterprise networked traffic has increased significantly, demonstrating the operating system has proven a popular choice for business users.

Exponential-e's analysis revealed the Apple originating traffic running over corporate networks was five times its usual levels on Wednesday 14th September, the day after the update was revealed.

The company suggested business users were rushing to install and try out the platform's new features. In total, enterprise network traffic increased by 30 per cent, which put extra demand on cloud services and data centres.

This trend continued the days after iOS 10 was released, with three times the normal Apple traffic on September 15th and double traffic coming from Apple devices on September 16th.

"As Apple seeks to defend its dominance in the smartphone market, it continues to set the rhythm of the industry,"Andrew Chant, head of networks at Exponential-esaid. "With the rise of mobile employees that are connecting their own devices to the workplace WiFi, organisations and carriers need to be prepared and expect to see a significant increase in network activity when Apple releases the latest iOS update."

Despite some people installing iOS 10 reporting the update destroyed their iPhones, this doesn't seem to have deterred business users. However, this extra traffic put pressure on many companies' networks and demonstrates the need for robust infrastructure to support spikes.

"While it's inevitable that accessing and downloading services on the same underlying infrastructure will spark an increase in data traffic, organisations need to be prepared with a scalable foundation that provides low latency and low-jitter connectivity to avoid any significant impact."

14/09/2016:It's the curse of early adopters: many people who updated to iOS 10 yesterday over Wi-Fi were hit with a series of confusing warning messages, though Apple has already addressed them.

Users reported that after they updated, their iPhone told them to connect it to a PC to update with iTunes, which simply brought another error message saying "There is a problem with the iPhone... that requires it to be updated or restored." To avoid the issue, make sure you have the latest version of iTunes installed.

If you are hit by the problem, you'll see a message on your iPhone telling you to plug it in to a PC so it can connect to iTunes. Your phone will then ask you to update or restore; clicking update will run the iOS 10 installation again.

Apple has already addressed the issue. "We experienced a brief issue with the software update process, affecting a small number of users during the first hour of availability," Apple said in a statement. "The problem was quickly resolved and we apologise to those customers. Anyone who was affected should connect to iTunes to complete the update or contact AppleCare for help."

13/09/2016:iOS 10 will finally be released to iPhone and iPad users at 6pm GMT this evening, just ahead of the iPhone 7's official retail launch this Friday.

As usual, device owners will be able to download the new operating system as a free software update from the iOS settings menu.

Fans are warned that they may face a long wait, however, as day-one demand for Apple's latest OS has historically outstripped the company's server capacity. Waiting until Thursday or Friday may lead to shorter overall download times.

09/09/2016:Beta users of iOS 10 can now get their hands on the final version of the operating system.

Apple has released the golden master (GM) to users on its Beta program, less than a week before the official release ends up in the hands of consumers.

The GM build should be the same software that will download to user's Mac, barring any last minute critical flaws. That version will be available from 13 September.

To get your hands on this version you need to sign up to Apple's beta testing program to receive the OS as an over-the-air update.

07/09/2016 UPDATE:iOS 10 will be available to download from 13 September, Apple has announced. The new OS will also come pre-loaded on the iPhone 7 and iPhone 7 Plus, which are available themselves for pre-order on 9 September and hit shelves one week later on 16 September.
