iPhone 5.1 Downgrade

[NineTails]

OK.
I have had a iPod Touch 2nd Generation jailbroken.
I saved my .shsh blobs on 4.2.1.
I am buying an iPhone on 5.1 tomorrow.
Can I use my .shsh that i saved w/ my ipod to
downgrade the iPhone to 4.2.1 so that i can upgrade
to 5.0.1 so i can have an untethered jailbreak?

no u cant...i asked the same thing and got this reply...

though untethered jb for 5.1 isnt far away....pod2g has allready said on this twitter account that his iphone 4 with 5.1 has now an untethered jb...

4S would be a problem...

Shsh blobs are unique and cannot be used with another device.

So im just better off waiting for a 5.1 untethered?

that's for you to decide I've been tethered before I survived.

Hmmm....
Tethered you just cant turn on your device if you turn it off right?
Might not be too bad..

Tethered jailbreaks work fine but you didn't state if your buying an iPhone that can run a tethered jailbreak. The iPhone 4S has no publicly available bootROM exploit and consequently no tethered jailbreak. iPhone 3GS & 4 are both vulnerable to 2 known bootROM exploits and therefore jailbroken for life albeit tethered only at times. If your new to jail breaking an iPhone 4 might be your best bet.

Well i wouldn't say im new to jailbreaking. I just have never had a tether jailbreak before, so i know nothing about it. I've been jailbreaking (untethered) since 3.1.3 . But i am buying a iPhone 3GS, for now, which runs on some other processor not A4 or A5
