Apple is outright lying here. "the technique could be used on any number of devices" - not since the iPhone 3GS! https://www.apple.com/customer-letter/answers/ …

@marcan42 can you extract SHSH blobs from a backup? It's certainly been possible to jailbreak devices after the 3GS.
@chrisFnicholson You can't downgrade an iPhone to an older, jailbreak-vulnerable version (unless you have the matching SHSH blob).

@marcan42 right, so my question is: can you get those blobs off of an iCloud backup, or do you need the unlocked device? -
@chrisFnicholson You need a jailbroken device to extract the blobs as far as I know. Definitely not in the backup. - Show replies

@marcan42 what prevents the government from compelling access to apple's private key? -
@chrisFnicholson Nothing. Same with their firmware signing key. If they did that they wouldn't need Apple's help either.
