On Monday, Apple previewed iOS 5, the latest version of the world’s most advanced mobile operating system, with over 200 new features that will be available as a free software update to iPad, iPhone, and iPod touch users this fall.

However, Apple  fans have no patience to wait for the upgrade. Yahoo! News reports that an Apple fan in Istanbul, Turkey has discovered a back door to upgrade to the new operating system (OS) without a developer account. Using Istanbul, Turkey  photographer Mert Erdir’s instructions, anyone can install the beta release of iOS 5, wrote Yahoo! News.

According to Yahoo! News, Erdir has published a video with instructions for the upgrade in his Twiter account. Although, the process is simple, the Yahoo! News reporter cautions people from using it and does not want to be responsible for any issues. 

As per this report, the reason for unavailability of uprade to iOS 5 is that the new version of iOS is still under development, and could also be unstable.

Meanwhile, wrote Yahoo! News, Apple may have already closed the back door found by Erdir. “I think Apple sent an update Over The Air to fix my workaround,” Erdir wrote on Twitter.

New iOS 5 features include Notification Center, an innovative way to easily view and manage notifications in one place without interruption, iMessage, a new messaging service that lets you send text messages, photos, and videos between all iOS 5 devices,  and Newsstand, a new way to purchase and organize your newspaper and magazine subscriptions. Apple said that iOS 5, iPad, iPhone, and iPod touch users can activate and set up new iOS devices right out of the box and get software updates over the air — no computer required.
