@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.

@chrisFnicholson Alternatively you can request them from Apple's server *at the time that version was actually current*, but not post-facto.

@marcan42 would apple's cracked version look the same? Put another way, can FBI request the blobs?

@chrisFnicholson Obviously they wouldn't be freely handing out signatures for the special firmware via their usual servers.

@marcan42 I mean, it's a signed version of iOS created by Apple. Point is, I don't think apple's language was misleading on its face.
