WARNING: Don’t Update To iOS 5.0.1 If You Want To Unlock iPhone 4S

by Rania Abdin on January 19, 2012

We’ve got some great news from MuscleNerd to those of you waiting for an iPhone 4S unlock. Although many warnings have suggested that iPhone 4S users update to iOS 5.0.1, MuscleNerd now advises iPhone 4S users to remain on iOS 5.0 if they want to unlock their device in the future. He confirmed that an untethered jailbreak for iPhone 4S running iOS 5 will be released right after the iOS 5.0.1 A5 untethered Jailbreak.

MuscleNerd has confirmed to iClarified that an untethered iPhone 4S jailbreak for iOS 5.0 will be released at the same time as the iOS 5.0.1 jailbreak, or a day or two later. As always, for those looking to unlock, it is standard operating procedure to stay at the lowest possible baseband.

If you are on iOS 5.0.1, downgrade to iOS 5, also check your build number and downgrade from build 9A406 to 9A405 while Apple is still signing both builds and stay at the lowest possible baseband.

While it’s not guaranteed now to unlock the iPhone 4S, back in November, MuscleNerd announced a very promising unlock for the iPhone 4S. So, make sure that you’re on iOS 5.0 if not downgrade and check your build number if you want to get your iPhone 4S unlocked.

If you found this post useful, hopefully hit the +1 (recommend) button ⇉

  • http://twitter.com/luissantana_a Luis Santana

    Can i still downgrade from 5.0.1 to 5.0 ?

  • Jon Watson

    oops.. misread

  • Jaredfonteles

    i suppose not, since he is talking about an unlock… unless you are thinking about unlocking your IPad 2…

  • Jason

    my 4s came with 5.0.1 on it. can it be unlocked and?or jailbroken???

  • Funny

    Remember that Muscle Nerd is hired by Apple that is why the advice is delayed

  • ZZ9

    i just wait for the 5.0.1 jailbreak for A5..
    if i understood it right the 5.0 A5 jailbreak and the 5.0.1 jailbreak will get released at the same time or the 5.0 a bit later.. so no need for me to downgrade :)

  • http://www.facebook.com/muha.alnahdy Muha Al-Nahdy

    Ipad 2 needs not Unlock .. All versions of IPAD 2 GSM MODELS are Factory Unlocked
    If you’re talking about ( UNLOCK ) if you’re asking about the next Jailbreak for the A5 Devices then it’s Better to be on 5.0.1 … :)
    hope it helped

  • Arturp93

    Downgrade to 405 for what???? If u want to jb the 4s or unlock it? Im on 406 and just want jb the 4s, should i downgrade to 405?

  • http://www.facebook.com/muha.alnahdy Muha Al-Nahdy

    Do iphone4 users have to Downgrade as well … As it’s kinda Odd… as the untethered jailbreak is on iOS-5.0.1 and downgrading would be hard for those who haven’t SAVED their SHSH blobs when they had their Tethered jailbreaks on iOs-5.0

    Hopefully you’ll Get this Clarified as it’s troubling some iphon4 users who’re keeping their fingers crossed for this Future UNLOCK.

  • Onavi97

    So this post is an advise for the UNLOCKING not for JAILBREAKING which are two different things, right?
    I have an iphone 4s fw 5.0.1 405…better to stay like that to make the jb as soon as it get released?
    Thanks for help!

  • Kittleboy

    how about iphone 4 4.11.08?
    should i also downgrade to 5.0?

  • Alfred Casale

    lololol. Wrong jailbreaker bud. The jailbreaker you’re thinking of is an “Intern” for Apple.

  • Alfred Casale

    …. They’re working on an unlock for the 4S… read the info

  • Guest

    Why has this site been suggesting an upgrade before the actual jailbreak comes out? Why don’t you just wait until all the facts are straight before you make suggestions? I’m finding another site to get information from, this one is whack.

  • Andrew

    I don’t quite get the point of unlocking and jailbreaking. Wouldn’t ypu want to stay with your plan? I know some companies charge an early termination fee. I’m very primitive on the whole unlocking hype, but, all it seems to me is just an iPhone that can function on any network. Is it really a big deal to do that? Or is there some other benefits to unlocking an iPhone. As far as I know, I just like customizing and getting cydia apps.

  • Joseph Provenzano

    So let me get this straight. If I wanted the 4S on an untethered jailbreak, I need it to be on 5.0.1, BUT if I wanted it unlocked I need to get it on 5.0. Wow…

  • http://www.facebook.com/profile.php?id=72602014 Alfonso De Armas

    My iPhone came with 5.0.1…is that a lost cause for me? Can I still downgrade?

  • Cobaltthegreat

    Someone dropped the ball. Biggest catch 22 I’ve seen to date.

  • Sucky38

    You’re a dumb fuck! Read it over and over again until you get it!

  • Sucky38

    Download ultrasnow from Cydia

  • Sucky38

    If you like getting Cydia apps and customizing then how come you don’t get the point of jailbreaking!?! Cause that what jailbreaking is for!!!!
    As for unlocking, people would prefer some network over other because the plan rate they are given is fair and their network has crappy ass phone and want the iPhone.

  • Lickpussy

    No one mentioned a ready iphone 4 unlock only iphone 4s is nearly complete

    Musclenerd only said he’s just working on it with NO ETA’s for iphone 4!

  • Randy_c

    THis is really stupid. One twitter mentioned upgrade to 5.0.1 now if you want to jailbreak and now keep iPhone 4S on 5.0 if you want to unlock.

  • Whitetigerdam

    Too Late!!!!!!!!!

  • Russexx

    Wow I’m surprised I’m reading something from someone that makes sense lol.

  • Abc

    any can tell me , is mean ?

    unlock iphone 4s = jailbreak iphone 4s


    unlock iphone 4s = unlock the iphone 4s baseband , to accept other sim card ?

  • Anonymous

    unlock iphone 4s = accept any sim card from any carrier/unlock baseband

    jailbreak is a different thing, it allows you to have cydia and download tweaks

    if apple is still signing 5.0, then it would be okay. What they would want people to do is downgrade back to 5.0 if they already updated to 5.0.1.

    What will happen is more or less like this scenario:

    1. downgrade to 5.0
    2. create a custom 5.0.1 firmware to keep the base band the same and not be updated
    3. Since its a custom firmware it already has cydia/jailbroken

    So unless apple isn’t signing 5.0 anymore, it won’t be much of a problem. (Though it would be a long process restoring back all the files again after downgrade) (sweat)

    Try downgrading it back to 5.0 since the post mentioned apple is still signing firmware 5.0

  • Anonymous

    I hope 4.11.08 gets an unlock soon. >_<

  • Anonymous

    Yes, this post is just for the people who wants to unlock their 4s. If you would like to stay on your carrier and just want the jailbreak, this isn’t a relevant topic in your case.

  • MacBeMe

  • IPhone 4s User

    My iPhone 4S came fully unlocked iOS 5.0.1.
    Also my baseband is : 9A405

    My Q is this.
    This came out of the box like this, & is it possible to dwngrade to 5.0 from my 5.0.1 without any backups.?

    Thanks in advance

  • Abc

    me too , pray hard

  • Anonymous

    been prayin everyday. lol! :) )

  • Kieran Colfer

    So, is 9A405 a 5.0 or a 5.0.1 build then? I upgraded to 5.0.1 build 9A405 on the grounds that everyone was saying it was ok to do this as the jailbreak would work, now I’m told it won’t work?
