iOS 9.0.1 is no longer signed for installation

iOS 9.0.1 installation is not signed by Apple starting today, the Cupertino blocking during this morning signed SHSH sites for iPhone, iPad and iPod Touch users sites.

Basically anyone who tries to do downgrade iOS 9.0.2 to iOS 9.0.1 or iOS 9.0.1 upgrade directly will only display an error by claiming that iTunes can not do this procedure and unfortunately there was no method of installing the iOS 9.0.1 at the moment.

It was expected Apple to unlock signing iOS 9.0.1 SHSH's for since the last more than a week since the iOS 9.0.2 was officially released to users, probably so few people is amazed this lock unexpected signature SHSH sites.

That said, starting today you can only reinstall iOS 9.0.2 on sites launched in the past years on the market, so do not try to do anything because it will not be possible in installing any other old version of operating system iPhone, iPad and iPod Touch's.
