The iOS 10.3 final version released a few days ago is a must-have upgrade for iPhone users. The successor of the iOS 10.2.1 contains critical bug fixes that prevent hacking.

One of the specific errors corrected by the latest Apple iOS concerns patching vulnerabilities of their software and iPhone device. It can be remembered that last year the US Emergency 911 contact center received thousands of calls leading to a chaotic situation.

An 18-year-old iPhone app developer reportedly unleashed a code online that threatened to take down the emergency 911 hotline. As a result, app developer Meetkumar Hiteshbhai Desai was arrested on charges of felony computer tampering, according to ArsTechnica.

The said act was perpetrated with the help of a Twitter account with more than 10,000 followers where the accused published a link that caused a person's phone to dial 911 without consent, according to Forbes. It is estimated that the link directing users to the 911 emergency number was clicked at least 117,502 times.

Apart from directing iPhone users to call 911, the malicious code also denied iPhone users the ability to take control of their device momentarily. Some users said that although they pressed the hang-up button, their device simply redialed 9-1-1. 

With the iOS 10.3 final version available online, users may freely update their iPhone software for added protection. With the help of the said bug fix available in the latest iOS release, iPhone users will be safe from potential hacks that could lead to their devices being used as an instrument of cybercrime.

Despite the latest Apple iOS, there is still no assurance that bugs or hacks may not occur. In retrospect, a software vulnerability which was supposedly fixed in iOS 3.0 back in 2008 resurfaced in iOS 10. Thus, suggesting a probable cycle of software glitches.
