How do I restore iphone 4 ios 5.0.1 that has been jailbroken with the recent hack?
Is it ok for me to just restore default ios 5.0.1 firmware via itunes?
I'm just making sure so I don't brick my phone..
The SHSH blobs are cryptographic signatures that should prevent us from downgrading to or restoring a version of iOS other than the latest. By saving them you can bypass this prevention, and later downgrade to 5.0.1 if you wish to jailbreak. The SHSH blobs are specific to each phone, and each version of iOS, so you have to save them yourself. It is very easy, just download TinyUmbrella and save them. Even better, save them and submit them to the Cydia server with redsn0w, then you can always downgrade.
So what if I'm not a jail breaker or have any plans of jail breaking should I worry about it still??
