If I have your PIN code, I can upgrade your device to iOS 11 and you haven't gained anything

  You don't need the password for an OS upgrade?!

    You need the device password (aka PIN code), not the iCloud password

      Which makes sense, because you can still run an iPhone without ever logging in to iCloud. It's extremely limiting, but it does work.

  Maybe I misremember, but after an iOS upgrade you have to sign into your Apple account again (at least I got asked every time). So knowing the passcode and upgrading from iOS 10 to 11 could mean the owner’s Apple account cannot be hijacked because the owner is not signed into the Apple account.

    From the article: "What if the iPhone in question runs an earlier version of iOS that does not allow removing backup passwords? I say you’re lucky because you can simply update that device to iOS 11 and then reset that password. We tried this strategy multiple times, and not once did we have an issue."

      Wait what? So if I have a device PIN I can reset an iCloud password from an iOS device without EVER entering the iCloud password?
