The iOS 7.1 jailbreak has been revealed for the iPhone, but it's not available for all models.

This week, a new video showing a jailbroken iPhone 4 running on iOS 7.1 was tweeted by user @winocom.

The iOS 7.1 jailbreak is currently available for older devices – the iPhone 4, 4^th generation iPod Touch and first-generation iPad.

See the video below:

The fact that the iOS 7.1 jailbreak was posted only for the older iPhone 4 means that newer devices are more difficult to jailbreak.

The latest iPhone 5S and iPhone 5 comes with additional security features pre-installed by Apple, making it difficult for hackers to jailbreak.

The Evad3rs have remained silent regarding the latest iOS 7.1 jailbreak by winocom. Could this mean that they are working on the iOS 7.1 jailbreak for the iPhone 4S, iPhone 5 and iPhone 5S?

Apple released its latest iOS 7 mobile operating system in September 2013. The initial launch was rocky, with thousands of users complaining of an error message when downloading the new software. Apple's servers struggled from the sheer number of people logging onto to download the software.

The Evad3rs team quickly followed with the first iOS 7 jailbreak solution in December.

Soon after, Apple released iOS 7.1, making the jailbreak more difficult for users.
