Blacksn0w RC2 Released To Unlock iOS 4

Blacksn0w - Unlock iPhone

We had reported last week that Blacksn0w, an extremely popular tool to unlock iPhone for iPhone OS 3.1.3 and iPhone OS 3.1.2 had been successfully ported to work with iPhone OS 4.0 Beta 4 and baseband 05.11.07.

Steve, the iPhone hacking expert who had released Blacksn0w RC2 for iPhone OS 3.1.3 has just released Blacksn0w RC2 for iOS 4.

This Blacksn0w port is based on modified binaries by msft.guy and the original Blacksn0w unlock released by Geohot.

Blacksn0w RC2 comes with the following release notes:

Use on Modem Firmware 05.11.07 ONLY!

V1.2: Support for 4.0 GM. Backwards compatible to 3.1.2/3 as well. V1.1: MyWi tethering fix

Geohot’s unlock for 3.1.2/3.1.3/4.0GM on the iPhone 3GS (and probably 3G). Please donate at if you enjoy.

With 3.1.3 & 4.0 GM patch (when needed) by msft.guy. Packaged by

This is an unofficial release but Geohot HAS given me permission to redistribute blacksn0w. All known issues with WiFi loss and boot loops seem to be fixed.  If it doesn’t work for some reason, you should still get the SpringBoard. This allows you to uninstall if necessary. It is a little slower to boot because of the increased safety of the release. A 3GS boots to cell connection established in about 90 seconds in iOS 4 now (50% slower than 3.1.X).

Improvements may be made in the future.

As we had mentioned earlier, this is not the perfect unlocking solution for iPhone users as it can only unlock baseband 05.11.07 that was included in iPhone OS 3.1.2. So if you want to unlock iOS 4, you’ll need to preserve the baseband using tools like iPhone Dev team’s PwnageTool to update your iPhone with iOS 4 rather than upgrading via iTunes when it is released on June 21.

We would recommend you to wait for iPhone DevTeam to release tools to jailbreak and unlock iOS 4, which they’ve announced will be available shortly after iOS  4 is released.

As always, we’ll keep you posted if there are any further updates so stay tuned here at iPhone Hacks or follow us on Twitter or subscribe to our RSS feed.

    Will this jailbreak 3gs 4.0 Gm 8a293 5.13.04

  • wolverinemarky


  • An0n

    Here, here. Just hurry up and release it. They say they can but how do we know? Could be false hope! Just release the fuckin unlock for baseband 5.12.1!!! Please..x

  • This doesn't jailbreak iOS 4, it only unlocks iOS 4 and baseband 05.11.07.

    It doesn't unlock baseband 05.13.04 thats included in iOS 4 GM nor does it unlock baseband 05.12.01.

    We'll need for iPhone Dev team to release tools to jailbreak and unlock iOS 4.

  • Mr. E Writer 3738

    They are posting to many false hopes of new unlocks for new OS when the real deal is unlocking baseband 5.12.xx. We the public know tha baseband 4.11.xx can be unlock, we get it. What the major population is waiting for Is the real unlock. Not this been there done that hack. If these hackers want the glory for a new hack they should do so by making a NEW hack not a copy of an old one.

    Here WHAT i need……
    Some one to release an unlock for (3gs 3.1.3-05.12.01)
    Spirit is the ONLY ONE with a jailbreak…But no unlock!
    I Don't have 3.1.2 SHSH…because spirit cydia wont give it to me. So….
    *I CAN'T downgrade to 3.1.2!
    *I CAN'T downgrade my baseband 05.12.01 to 04.26.08!
    *I CAN'T but 3.1.2 shsh using AutoSHSH from sn0wbreez!
    *I CAN'T use Sn0wbreez jailbreak for baseband 05.12.01
    *I CAN'T even use blackra1n

    Spirit is THE ONLY ONE with a Jailbreak but even they arn't smart enough to unlock it.

    ALL I am asking is to unlock my FUCKING Sim card.

  • Br1an

    Wow. Pretty harsh on someone doing the community a favor when there's really no obligation.
    if you don't like it I guess your options are
    1)Switch phones and shut the fuck up.
    2)Learn code, do it yourself and shut the fuck up.
    3)Be thankful there are people out there doing any of this jailbreaking and unlocking…and then shut the fuck up.
    Nothing worse than ungreatful fucks!

  • Adrian

    wow, what a ungrateful bunch of pricks, if you need a unlock you shouldn't of updated. like some one said earlier get a new phone and shut up, or learn code and do it yourself.

    i have a 3gs running 3.1.2. if you have been in this game long enough (which most people complaining arn't) you should automatically know not to update till devs or geohot say something. mostly saurik say something on cydia. so sorry to hear about your damn problem but shouldn't have been so ignorant.

    your damn lucky they don't charge to release unlocks you ungrateful bunch or idiots.

  • Chris

    Wow lots of frustration here , i am also waiting for a long time for a solution …. My 32gb 3gs iphone is waiting since nov 2009! Luckily i have a 16gb gs working perfectly 🙂

    I hate to see aggressive remarks and very demanding demands towards the good folks spending their time to get us the unlock for baseband 05.12.01 / 3.13

    So good thanks to all the volunteers and thanks , we will be patient , sorry for all these nasty remarks….

  • Gully

    Well done Br1an.

  • J0hnn3

    Those of you who write comments to be an disrespectful to the people disrespecting others. Give it a break, kissing butt don't get you guys brownie points for defending the programmers that are repeativtly doing the same useless hacks, and if you're going to leave a comment be mature leave the trash talk in your homes cause they don't help in proving your points across to anyone.

  • yeya

    Shut the fuck up everyone 😀

  • Ok here is what I have to say
    I been waiting months for this unlock ever since I bought my 16gb gs phone
    infact I been using it in o2 but I want to use a orange sim
    to all the nasty people with the horrible comments I hope the unlocking process goes wrong for you
    the iPhone dev team have put a lot out there for us all to get the most out of our phones
    I'm a blogger, I know what it feels like to supply files for people to download, it feels great helping others
    like the previous posts if your so frustrated then learn it your self and stop bothering the dev team
    to the iPhone dev team I love you guys man. Great work on everything
    people please wait for the unlock, it won't be long from now
    this is [Supaa Stahh Marioo<<<< facebook name]



  • Mario

    Wow everyone ones a critic… Shut the fuck up… Good post Brian

  • GMan

    Thank you !!!!! Who the fuck does he think he is ????

  • GMan

    Then do it big boy !!!!!!!

  • suckitbitch


  • P_NY

    Yup Im with u on that one

  • hunnyluv78

    Damn, people are super mad…the Dev team/Geohot or anybody else has to release anything? Calm the fuck down…why did you buy the iphone if you didn't want sorry azz at&t?

  • Kai

    LOFL. I hope those angry 'unlock-my-iphone' jerks are all teenage boys with calloused hands from too much masturbation. I am one of those accidently suckers that updated to 3.1.3 and my phone has been carrier locked ever since. It is essentially a mini-iPad with no processing power.

    If I was a dev, I'd be hard pressed to want to stay in the game with knobs like you guys out there yelling about 'needing a fix'. Patience, all will be headed in the right direction post iOS4 public release.

    Calm the fuck down and take a valium or something. Get back to your porn, vaseline, and box of tissues.


  • Z

    seriously, ive just learned not to argue online (AHEM, WTF and An0n. fuckers) because you will NEVER win, either way whether or not you're wrong and douchebag-ish (WTF, An0n) or right (everyone else)

  • Jcm800

    Well said, ungrateful gits

  • c

    Thanks for all the work, I know I can't do this, even though I can't wait I am appreciative and more ppl should be. Nice to see some positive remarks here!

  • Alexx_ROU

    First off, I wanna thank all the hackers who are providing us with these hacks, you guys are awesome, keep up the good work. I have an iPhone 3Gs from America,I am in Romania right now, of course i was dumb enough to upgrade to 3.1.3 the very first day i got my hands on the phone, oh well, my question is, what will be the way to go for the unlock? Upgrade to 4.0 then apply the unlock and jailbreak when available? And in order to re-activate my phone, considering it was brought form America, do I need an AT&T sim card? I can order those online.
    Frustration is high with the 3.1.3, I have had my phone for a few months now and it only collects dust, but I have faith in you guys! Thank you and lets hope we can get everyone happy soon!

  • Dudley

    Well Done Br1an… Too Many ungrateful Fuckers out there.

  • Benzo

    I've used the unlock and it works great! I'm just having trouble with the MMS recieving. Is anyone else having/had this issue? How did you resolve?

  • akri

    people..why the profanity and bad attitude? these people are doing us a favor..they have no need to do this for us yet they do…be grateful and thankful! I for one love you hackers and iphone hacks for always keeping us posted w/the latest news and updates..ignore those idiots..they're not worthy of our community.

  • si

    Yep I hear u WTF

    We need unlock for 3.1.3 (5.12.1 modem)

    Pleaseeeeeeeeeeeeeeeeeeee tell us when we can unlock this!!!

    Simon London

  • badboy

    WTF!! devs already have an unlock for 05.12.01 but they dont wanna release it -_-'.

    @ akri – hey ass wipe. fuck off.

  • Jayb

    I bet none of these JErks have donated one cent to the dev teams and there here bitching and moning about how they want this and that STFU !!!!!!!!!

  • apple hatter

    awsome work ……… thanks for your generous, but we all need unlock tool for 3.1.3 05.12.01 for all devices

  • mark

    I have 2 iphones on Orange and o2 (uk), i jiust paid the money to Orange (O2 free) to have them unlocked. IOS 4 gives me what I Jailbroke for, so I wont bother with unlocks or jailbreaks anymore now, i cant bear the suspense waiting for them to be released 🙂

  • chest nut

    For all of you ungrateful mofos who need to unlock your phone, try this super UNLOCK method: 1: soak your iphone in butter 2: place inside a microwave and set timer for 10 minutes. 3: press start and your done.

    Thanks to iphone dev team for your hard works! You guys are brilliant!!!

  • Rupesh

    I tried that and now my phone doesn't work! WTF dude!!!!????

    I couldn't resist posting this sarcastic comment. I feel sad that there are people out there who will actually try this.

  • I can’t help but admire the i Phone Dev team doing all this work for free or just donations, and as for all of you hew are bitching, you are all a bunch of ungrateful bustards

  • j

    what a bunch off crap. aaaaaah im as frustrated as all you lot waiting for the bb 5.12.1 unlock. as my phone is locked. but i live in uk with an at&t locked 3g. i aint even got a choice just have to wait for a unlock! and if i could read code i would be more then happy to help these legends with there incredible work.

  • u dont know me

    everyone can shut the fuck up because im using att

  • Hmmm

    Wow, to all those DEMANDING the dev team release the unlock RIGHT NOW, I'm just curious – from where does this sense of entitlement come from? I mean, obviously you all DESERVE to get this for free – at least that's what you're saying – so why is it that you're ENTITLED to this, to the point where you'll scream and curse and demand more free work from people that you don't know?

  • steph

    you're just talking about unlocking iphone 4.0 but when will we be able to unlock the 3.1.3 version of the iphone?? i have a 3gs sleeping in his box and i must use an old nokia phone for about 2 month. i can't use it and i can't sell it. i can't do anything!!!!!

  • dknz

    Me too man I also fucked my self in the ass by updating to 3.1.3 (base band 5.12.1) on my 3gs 16GB
    So I'm patiently waiting for GeoHot or the Spirit People Or iphone DEV team or some other genius to provide me with an unlock.
    Meanwhile I am enjoying my jailbroken iphone with spirit as an ipod touch!
    I do realize of course that everyone is waiting for the official release of the 4g IOS on the 24th of June 2010. I just hope that it comes soon after that.
    Thanks again guys for all your hundreds of hours of hacking and coding.
    We are grateful.

  • yeyex

    since when this formum become swearing-forum…

    well i have 5.12.1 and tried to unlock it last time..with blacksnow FAILED..with snow..watever it called..FAILED..
    last 1 i used spirit and it works.
    but i cant use the mms system

  • Why sit on the latest unlock but release an unlock for a phone that isnt even out yet? it makes no ends nobody cares about how hard you guys work we all know your gonna do it anyway just release the baseband 05.12.1 unlock or atlesat stop teasin us with bullshit. Most of your news is bollocks anyway not to mention mainly wrong… Also trolls as your gonna jump on this as your lifes have no meaning fuck you and all

  • fuck of

    yeyex how did u unlock by spirit ?

  • Thomas

    Hahahah tru

  • S33KY84

    WTF, why are there so many self rightgeous assholes up here? So what people are frustrated because, they been saying since February that an unlock was coming out and here it is June, and a new iphone is coming out and still no unlock. So many people are stuck without their phones for various reasons, whether they upgraded by mistake or they had no choice but to connect to itunes because their phones crashed, either way, who the fuck are you to criticize someone because they want to use their fucking phone. Seriously your the ignorant one, because you take the time to go through blogs and try to put somebody down through a message, grow up and get a life, lame.

  • monk with pebble in hand

    you guys that are complaining dont get it do you?

    if the dev team/black rain/ whomever… releases the 3.1.3 – 5.12.01 hack BEFORE the official release of the new iphone os… APPLE WILL FIX IT AND ALL THAT WORK WOULD BE FOR NO REASON.

    if you read (and can understand) what this post is about, its not to tease us. but i quote " All known issues with WiFi loss and boot loops seem to be fixed." its a fix for 5.11.07 bb issues.

    if dev team release the 5.12.07 prior to the hard release of the new iphone… apple will see where their fudge up is and fix it.

    i failed on my first attempt to hack and had to update not realizing the bb i installed f'd me for the next 5 months >.<

    sht happens… im as eager as the rest of you ungrateful fwks to get the update and as irritated as well… but wtf can we do about it? complain to the point where the dev teams says f all of us?

    patience grasshopper

  • please can anyone tell me when will 3.1.3 (05.12.01) unlocking is actually coming out..

  • uh oh. hopefully this doesnt apply to 3.1.3 too!

    "@musclenerd: At the risk of confusing those waiting for 05.12 unlock… (ultrasn0w for 4.0, 04.26.08 only!)"

  • paranoid

  • iPhone 4 will come bundled with iOS 4. The baseband in iOS 4 GM is 05.13.04. Dev team have confirmed that it is possible to unlock baseband 05.13.04 and 05.12.01.

  • Ryan

    will I be able to jailbreak and unlock my phone in a week or so if I upgrade to 4.0 now? or should I wait and only upgrade to 4.0 when the dev team says they have the unlock? because I don't want to be stuck like 3.1.3 users were when they upgraded. thanks guys

  • james
