I have a jailbroken iPad2 with 5.1.1. Had saved the shsh blobs for this but did not update because I thought iOS 6 was not going to be jailbroken. Now 6.1.2 is jailbroken but my device shows update available to 6.1.3. Can I update only to 6.1.2 and jailbreak it? How? Will I be able to restore my apps and games?
