Did you upgrade your device to iOS7 and realized you do not like it and want to downgrade it back to iOS6.x? How it can be done?
Short answer: It cannot be done.
Long answer: It can be done for a short time when Apple is still signing older version of iOS for your device. After iOS7 release this period of time was extremely short, so if you have device which is supported by iOS7 and you upgraded there is no way back. Current “signing status” can be found foir example on following page: www.icj.me/ios/all.
Lesson learned? Think at least twice before upgrading next time:-)
