instal the new version for iphoneMafia 4

This wikipedia page contains a list of iOS devices & the latest iOS they can support. See this article for some general information around this topic.

If you had previously Jailbroken your device on iOS 6, it may be possible, providing you have saved your 'SHSH blobs' which can 'sign' the install instead of Apple.

Once a new version comes out, Apple stops signing previous releases to keep everyone running the same iOS version and to prevent you from jailbraking your device again after restoring by forcing you to do an update. Putting a newer iOS on older hardware that never even supported that OS is near impossible.Īs part of the iOS restore process, iTunes has to check with Apple's servers to 'sign' each install of iOS just like App Store apps must be signed to run.

This signing window typically is closed within days of a new version shipping. Downgrading or upgrading to a no longer current version of iOS is generally not possible once Apple stops signing the old software, as is needed when iTunes is preparing to install or restore an iOS.
