Is it possible to upgrade to iOS 6.1.2 on iPhone?

My iPhone (iOS 5.0.1) is jailbroken and I've backed up all my Cydia packages, etc. Even though iOS 6.1.3 is out, I want to upgrade to iOS 6.1.2. Reason being is there's no jailbreak out for iOS 6.1.3.So is it possible to upgrade to iOS 6.1.2 atm?

Unfortunately there's no way to update your iPhone to IOS 6.1.2. Apple always wants people to upgrade to new IOSs because they don't want people to take advantage of the flaws in the previous IOS which they fix in the newest version of the IOS. Therefore, they will stop signing software such as IOS 6.1.2 so everyone who wants to backup will have to backup to IOS 6.1.3.

Not unless your restore your iPhone >> Then Update >> Then Re-jailbreak to iOS 6.1.3. Link to jailbreak is here: http://www.dailymotion.com/video/xz5xed

You can't update to 6.1.2 because apple have stopped signing that firmware. You can only update if you have the shsh blob saved
