UltraSn0w Unlock for iOS 4.2.1 is Ready for Sunday!

MuscleNerd confirms that UltraSn0w unlock for iOS 4.2.1 is ready to release. UltraSn0w to unlock iOS 4.2.1 will be released tomorrow as previously confirmed by MuscleNerd.

ultrasn0w unlock ios 4.2.1

This is what MuscleNerd has tweeted:

“Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization.”

This UltraSn0w update will unlock iPhone 3G and iPhone 3GS only. iPhone 4 iOS 4.2.1 unlock will take some more time. Dev-Team had planned to release UltraSn0w update shortly after the iOS 4.2 availability but was delayed due to unexpected update.

We’ll keep you posted as soon as UltraSn0w for iOS 4.2.1 is released. Stay Tuned!

I have a Iphone 3gs jailbroken unlocked firmware: 5.12.01 version 3.1.3 (7E18)

I don’t know if it’s old or new bootrom….
can i update to 4.2.1 and unlock with ultrasnow ?????

please answer, i am a new one 🙁

thanksssssss 🙂

AfRoO November 27, 2010, 7:32 pm

yes u can but don’t forget to save ur SHSH, so u could downgrade ur iPHONE IN FUTURE Whenever u want,

Ordinary_guyz November 27, 2010, 8:32 pm

Well I think u shouldnt upgrade to 4.2.1just yet because then u will end up having a tether jailbreak iPhone and that’s kinda annoying. You should wait for dev team to release the untethered jailbreak.

AfRoO November 27, 2010, 10:30 pm

well man stop it, I just seen dev team twitted saying

Question: What about new-bootroom devices? is it gonna cover them is well?
Answer: The unlock will cover 3GS devices that are currently tethered JB at 4.2.1, but you’d still need to tether JB them for now
Question: So will it work on new-bootrom 3GS 4.1/05.14.02? Or does it need 4.2.1?
Answer: Nope it doesn’t need 4.2.1…but we needed to make it to work on 4.2.1. For new-bootrom 3GS, 4.1 is best for now
Question: What about new-bootroom devices? is it gonna cover them is well?
Answer : I’d stay at 4.1 if I were on a new-bootrom 3GS, until the untether JB 4.2.1 comes out

that’s mean for the old bootroom only whos can upgrade to 4.2 but new bootroom stay on 4.1,
to know ur bootroom check out iPHONEHEAET.com old catalog, guys teached us one day how to know ur bootroom.

good luck

Ordinary_guyz November 28, 2010, 9:52 pm

Lolz.. Thanks for filling out my missing info.. Yes I’m talking about the new bootrom tat is a tethered jb. ;p.. Man.. Only 10 more minutes to go until 10am.. Someone here said the unlock will come out at 10am.. I keep my finger crossed.

AfRoO November 27, 2010, 7:32 pm

that’s great \m/

paarthforu November 27, 2010, 8:12 pm

Yes u can unlock ur iphone 3GS 4.2.1 Baseband 05.14.02 or 05.15.01 anything….New or Old Bootrom

Ultrasnow out tomorrow. Just follow the step and Jailbreak and Unlock ur Device.

Rpl if u hav any hesitation about JB and Unlock iDevices.

ferrara5 November 28, 2010, 9:27 pm

Ok I have 4.2.1 (bb 5.15.04 bl 6.02)do I jailbreak it with redsnow or downgrade to 4.1 and jb it, if downgrade which jb do I use. Are any of these jb untethered?

moodi November 29, 2010, 12:21 am

Nop , Please don’t let people do the mistake. It will unlock old and new but also it will be tethered and that is a pine in the ass. I think for new bootloader it is better to wait .

Ordinary_guyz November 27, 2010, 8:34 pm

By the way I’m in Cambodia.. It’s GMT +7. so when u are mention Sunday… Which time is it?

AfRoO November 28, 2010, 12:55 pm

it will if ur iPHONE 3Gs on iOS 4.1 old/new bootloader or 4.2.1 Old bootloader ONLY
iPHONE4, maybe Monday and maybe longer

Irvin November 28, 2010, 12:33 am

Does it only work on 4.1 and 4.2? I’m thinking of down grading my iphone 3gs to 3.* for better battery life, the damn phone barely works for half a day without charging. And I’m not even making any calls either due to it being locked.

Worst battery life of any phone I’ve owned.

BTW anyone know which fireware got the best battery life?

Ordinary_guyz November 28, 2010, 9:30 pm

For my experience… Using custom firmware 4.1 on 3GS or i4, the battery life is suck. However if I restore with the official firmware and jailbreak with greenposion or limera1n, the battery seem to last longer..

So are u restoring with the official one or custom?

shipon1991 November 28, 2010, 5:11 am

hi, i accidentely updated to 4.2.1 coz i thought the unlock was out for my baseband 05.15.04 but it isnt yet iz this sunday one gna unlock my 05.15.04

khalique November 28, 2010, 9:16 pm

In asia, 2 hours left to finish sunday

Ordinary_guyz November 28, 2010, 9:45 pm

Guyz… Look, let say the unlock 4.2.1 is already out for all iDevice.. I suggest u guys to take care of your precious device without messing it all up and then end up whining for jailbreak or unlock 4.3, example.

I think people using iPhone are advance users So before u wanna upgrade or anything please give a minute to visit this site or googling on Internet. I’m pretty sure there will be information about the thing that u wanna do.

People in iphonehacks are friendly, if u have any question just drop a comment, they will try their best to answer to ur question.

It’s kinda funny when I looked back in the past when everyone is waiting for the unlock 3.1.3. Dev team are trying so hard to release the unlock 3.1.3. But then a few weeks later, there are people end up locking their phone to 4.0 and whining for unlock 4.0. Then dev team trying hard again to find a way to unlock 4.0 until they made it. And now we are whining for 4.1… I bet next time when apple release 4.3, there will be more people whining for 4.3 unlock.. Haha!

I mean, if u have an iPhone but not an advance users, u should seek for someone who know a little more than u do for help.. They won’t mind helping u out right?

Hey above are just my opinion. No offends..

AssistAxel November 28, 2010, 10:28 pm

I ve a question, because I am not sure now anymore:

I can jailbreak my 3G but is cydia working on 4.2.1 jb?

Because id not I cant install ultrasn0w either.

~

fock u dev team November 28, 2010, 10:30 pm
