Many iPhone users must be wondering whether or not to stay on 6.1.3/6.1.4 or upgrade to iOS 7. This might help you a little bit about that so please read carefully.
For iPhone 4 user
If you have not ready, make sure you save your iOS 6.1.3 blobs with iFaith, TinyUmbrella or redsn0w (ipsw required). There’s a lot of confusion about having to be running iOS 6.1.3 to obtain such blobs. Actually that requirement only applies if you’re dumping blobs right off the device. We also have to mention that if you have a firmware below 6.1.3 and do not have SHSH blobs for it, make sure to grab those blobs with iFaith. If you obtain these SHSH blobs, you’re free to upgarde to iOS 7 and downgrade back down in case of anything getting released. (Does not apply to A5 users)
Having a device with an A5 processor or higher
If anyone is currently on iOS 7, you should downgrade to 6.1.3/6.1.4 because there’s currently a potential 6.1.3/6.1.4 untethered A5+ jailbreak being pushed in the upcoming days/weeks.
If you wish to be included if such thing takes place, downgrade now while you still can. Once iOS 7 goes live later, the 6.1.3/6.1.4 signing window will be closed real fast.
If you’re on 6.1.3/6.1.4, today is your last chance to restore and get a fresh start. If you’re jailroken on 6.0 to 6.1.2 with evasi0n, stay where you are.
One more thing left, if you want to donate for an A5+ 6.1.3/6.1.4 jailbreak/BETA, the person you should donate to is no one. Any credible “jailbreak dev” will not ask for donations in advance to create a jailbreak.
