Before iOS 7 was released, we told you the reasons why you shouldn't upgrade your iPhone, iPad and iPod touch. One of the many reasons we've cited is that upon upgrading to iOS 7, Apple will make sure that you will not be able to downgrade. So if you don't like the iOS 7 experience or perhaps you miss your jailbreak, it seems you are now out of luck as Apple has stopped signing iOS 6.1.4 (for iPhone 5) and iOS 6.1.3.
Sn0wbreeze developer iH8sn0w has confirmed via Twitter that Apple has stopped signing iOS 6.1.3/6.1.4. In case you don't know, if Apple stops signing a firmware, downgrading or restoring to that firmware isn't possible anymore. This is remedied by saving SHSH blobs but the method has become less reliable now.
Looks like Apple is finally starting to stop signing 6.1.3/6.1.4.

Just to be clear, you will not be able to downgrade to iOS 6.1.3/6.1.4 even if you have your SHSH blobs saved. For some reason though, the iOS 6.1.3 firmware file for iPad mini (GSM model) is still being signed but we doubt that it's going to stay that way for long.
This shouldn't be a surprise for most of you as this is Apple's strategy to cut down jailbreak users. Upon releasing new software updates that fix jailbreak vulnerabilities, the company will also stop signing older firmware versions to ensure that there's no going back.
So if you have a jailbroken device below iOS 6.1.3 and isn't too keen on losing your jailbreak, then you might want to be extra careful and not do something that will require you to restore. If you are willing to wait, the Evad3rs dev team is already working on the iOS 7 jailbreak but don't count on its release in the near future.
