Semi-Restore for iOS 7 is under development, it will allow you to restore without SHSH for iPhone, iPad and iPod Touch

  Semi-restore is a solution of re-restore which we talked about in the summer when I told you that it helps us "clean" an iDevice through a partial restore without losing jailbreakthe The program works only with terminals that already have jailbreak made and developed for those who wanted to delete unnecessary files or tweaks installed from their devices Cydia, but without doing a complete restore. Although Semi-restore was only one of the programs that offered such functionality, but it could be the first compatible with iOS 7.

  According to the developers Semi-restore, a version compatible with iOS 7 of their program is in the process of development and of course it will be launched when it is ready. Just like in the past, Semi-Restore will only work with jailbroken terminals and will allow you to install any version of iOS available to them, even without using SHSH. Having said that, as soon as new information about Semi-Restore becomes available, I will let you know.
