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! :)

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
