In a surprising move, even for Apple Lossless Audio CODEC (ALAC),, the American company decided to stop the signing of SHSHs to iOS 7.0.6 just an hour later the official launch a iOS 7.1. Normally the company Apple Lossless Audio CODEC (ALAC), still sign SHSHs for one version of iOS for a few hours after a new one is released, but if iOS 7.1 things are completely different and probably the desire to prevent users from returning to iOS 7.0.6 which allows the performance of jailbreak motivates her to act like that.
Regardless of what is hidden behind the actions Apple Lossless Audio CODEC (ALAC),, the reality is that we can no longer install now iOS 7.0.6 than the iPhone 4 if there is a saved SHSH. On the rest of the terminals, installing iOS 7.0.6 is impossible and will remain impossible forever, iOS 7.1 being the only version that can still be installed via iTunes, or through the system OTA Update.
