SemiRestore for iOS 7 will be available soon, it will allow you to restore without SHSH

  I told you at the beginning of this year as the developer of the program SemiRestore started updating his creation to be compatible with iOS 7 and to allow us to do re-restore without using a SHSHSemiRestore 1.0.5 or 2.0 will be released for iOS 7 and he would be compatible with everything iPhone, iPad or iPod Touchthe ones that have jailbreak made using evasi0n7. The program will work only on jailbroken terminals and will perform a re-restore without actually reinstalling the entire operating system.

  At the moment the same program is available for terminals running iOS 6 jailbroken using p0sixspwn and allow the complete cleaning of the operating system without performing a full restore that requires SHSH. It is not yet known when the new version will be available SemiRestore, but it can initially only be used on Windows computers, so if you have a Mac you will have to wait.
