    Well, the title says what I'm after. Here's the situation:

    - iPhone 4
    - Currently on iOS 7.1.1
    - Want to downgrade to iOS 5.1.1
    - Was delivered with iOS 4.0.2 (or 4.1)
    - Has never been jailbroken
    - Do not have own shsh blobs
    - Can get blobs from another iPhone 4 with iOS 5.1.1
    - Want it untethered

    I've googled around and found out that is possible. There are however a few things I haven't figured out.
    1. Will the jailbreak (and downgrade) be tethered or untethered? One source says it will be tethered, but googling "ios 5.1.1 untethered" says it's possible.

    2. Can I put the device to sleep? A source claims that without the correct blobs, putting the phone to sleep will cause reboots (or whatever it was).

    3. Will my iPhone be changed permanently? I know that you can just restore, but when you jailbreak, are there files written to some kind of funky hidden-away memory on the phone, or something similiar?

    Is there something else I should know before I proceed? Any tips or experience you want to share?

    (I know I should just learn to live with iOS 7, but I don't want to! If it's possible to get iOS 5.1.1, I would really want to try at least.)

    Thanks for reading! :)

    You cannot downgrade with SHSH blobs for the target firmware for your device.

    The blobs must also be from your device. You cannot use someone elses blobs to downgrade.

    you're better off looking for a second hand iphone 4 that hasn't been updated
