Apple uses iOS to run their products like iPhone, iPad, iPod touch and apple TV. We can say iOS must be one of the operating systems like windows, Linux and Android. It hadn’t an official name until the release of iPhone SDK (iPhone software development kit). At the beginning they simply named it OS X. After that it was named iPhone OS. Later the Apple suggested using this operating system for their other products too. With this incident it was renamed iOS in June 7, 2010.
First version of the iOS was released in June 29, 2007 concurrently with the first iPhone. After that lot of versions of iOS has been released by Apple. iOS 5.1.1 is the latest invention for iPhone 4s and other idevices. They will release iOS 6 recently with new features.
These iOS versions were popular among the customers. They were customer friendly and faster system than other famous operating systems like Android. People loved iOS very much and Apple wanted to fulfill their customers’ necessities totally. According to the apple there are over 200 new features in iOS. Meanwhile other mobile phone companies also tried to fight against this system. These are the reasons that Apple had to develop their iOS continually.
In October 2007 Steve Jobs, the former CEO of Apple Inc. made an announcement that new software development kit (SDK) which can used by the third party developers. It is said, a person who wants to be a developer of iOS should be paid $99.In 2010 Apple brought out new development kit called X code. Those developers are given an opportunity to decide the prices of their developed applications. But 70% of the profit goes to the developer and rest of that goes to the Apple. So called developers were the pioneers who upgraded the standards of iOS. They tried hard to upgrade the iOS because of the reasons mentioned above.
They also wanted to make it strong that cannot be jailbroken.
But unfortunately they couldn’t discourage jailbreakers of the world. Presently this Jailbreaking community of the world is capable of breaking the latest versions like A5 and A5 x.
