The iPhone Dev-Team has announced that they have successfully untethered the jailbreak for iOS 4.2.1 for those with their 4.2b3 hashes saved.

MuscleNerd recently tweeted, Got "backup plan" for untethered 4.2.1 JB working (video coming up). Uses mysterious 4.2b3 hashes Cydia kept for you.

(It's a "backup plan" because comex is working on a more extensible one, but this method is also generalizable)



We'll keep you up to date with more information as it develops.

Update:
MuscleNerd has confirmed that this will work with AppleTV 2G 4.2.1 too.

Update x2:
Comex has said that we'll get an untethered jailbreak by Christmas.

Hey. Watch your words!! The jailbreak isnt ready yet, that means isnt stable and it doesnt work for ALL devices on 4.2.1. So STFO and GTFO or just be quiet and wait for good guys to release the jailbreak. They are doing that for FREE. U could donate some money...

Wait I left out that I want to upgrade to 4.2 and I hv old bootrom
Thatcher

There is a way.....But this is not the safest way and you will definitely invalidate your warranty. It involves installing a iPad baseband which is very detectable by apple. I would wait
TheRose
TheRose - December 8, 2010 at 3:07pm
I know that but it seems risky even though my warranty expired. Can pwnagetool upgrade my phone while preserving my bb?
Thatcher
Thatcher - December 8, 2010 at 3:28pm
No, it installs a custom iPad Baseband. it isn't excluded from the upgrade as Apple introduced a BB check on firmware 4.2.1
TheRose
TheRose - December 8, 2010 at 4:03pm
I think it's risky because if I upgrade to a iPad bb then then wt happen if apple release a new version with old bb. I'm scared of not being able to go back. So in conclusion with 3GS old bootrom 4.0.1 bb 5.13.4 if I need to UL, I either upgrade to the iPad bb or wait? And wait for wt specifically, redsn0w bundle? Comex? Pwnagetool bundle then redsn0w?

Don't even think about iPad BB upgrade, sooner or later you will brick your iPhone, the same thing has happened about two years ago with iPhone 2G "no imei, no wifi, no bt". Then, new iPhone version will come out and everyone will focus on that, you will remain with a nice, shiny and expensive paper weight. Seems like dev team don't give a fuck about all the problems they caused in the past.

What if I have a just bought iPhone 4, running iOS 4.1, Will I be able to upgrade to 4.2.1 and unlock it without tethering it? Thanks in advance...
Thatcher
Thatcher - December 8, 2010 at 3:00pm
At the moment, the only devices that aren't tethered are older NON MC models. This does not include the iPhone 4. If you want my advice, stay on 4.1 until there is a fully untethered version of the Jailbreak.

teraflow - December 8, 2010 at 3:48pm
Thanks, I'll do that Quick question, will I be able to unlock it on iOS 4.1? I don't know what baseband it's running since I didn't receive it yet, but I think it's running the 4.1 one Thanks!
