Apple announced the latest upgrade to iPhone OS 3.1 – firmware version 3.1.2 early last week and if you are waiting to jailbreak iPhone OS 3.1.2, the sad news is that the iPhone Dev team is yet to release the Pwnage and redsn0w tools. But the good news is that, if you are waiting to jailbreak your iPhone, GeoHot has just released BlackRa1n, which will allow Windows users to jailbreak their iPhone with OS 3.1.2.


Jailbreak iPhone 3.1.2 OS with Blackrain

Warning: The current update of Blackra1n only supports iPhone OS 3.1.2, do NOT use this tool if you are using an earlier version of iPhone OS. We have unconfirmed reports that BlackRa1n supports iPhone OS 3.1 as well, but we are not sure.

Also, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded.


Download Blackra1n for iPhone/iPod Touch

You can download BlackRa1n to jailbreak iPhone and iPod Touch OS 3.1.2:

Once downloaded, make sure to update your iTunes to the latest version.

  1. I just downloaded blackrain, just waiting cydia and rock to download – hope it works, fingers crossed. Have to say, installing blackrain was super fast.

  2. Hi, im Wondering if blackra1n is for iphone with current OS 3.1.2? or 3.1? And how do i update it after downloading.

    • update thru itunes, if you are on a different provider other than att do not use black rain to jailbreak your phone.blackrain uses itunes software update and it will update your baseband making your phone unlockacble

  3. Ok, call me dumb.. But I cant clicky on the thingy to downlaod Blackra1n! O_O I only want to Jailbreak my phone so I can get a ringtone that Apple doesn’t give 😛 I am not greedy.. … Oh and, What other firmware/software do I need besides this? Because when I jailbroke my phone with Redsn0w previously, I needed two different files….

  4. Does Black rain work on touch ipod with 3.2 ? My ipod has not been jailbroken at all. Do I need to do this first, or just break it with Black rain? Thanks Leo

  5. 1. Start with a clean firmware. Update using Itune.
    2. Install BlackRain in your PC.
    3. Run Blackrain.
    4. On your IP run the app, twice. This will prepare the IP for Tethering.
    5. Download Att profile from the Internet and install
    6. Reboot and viola!!!!!!

  6. So i just downloaded blackrain and it works great, but having sum issues, when i download the “Mac Book Black Keyboard thru Cydia and then try to use it thru winterboard it will not switch, it stays the basic iphone keyboard…am i doing something wrong?? help!!

  7. i have jailbroken and unlocked my iphone by blackra1n it seems that i have the updated rom.(tethered jailbreak.), whenever battery dies i need to rerun the blackra1n again . does anyone have solution for this.

        • I presume the issue relates to not being tethered (don’t understand this) to a network. Which thought was the idea of unlocking. I want to be able to swap sims as I move to different countries. Pretty limited solution if you have to reload every thing each time the battery dies or you turn the phone off. Any ideas greatly appreciated

  8. well, i just made it rain LOL and im kind of scared cause it all happened so fast but ill be sure to let u all know if it worked, [*fingers, toes, arms, and legs all crossed*]

  9. So Ive managed to seemingly jailbreak my iPhone 2.G w/ 3.1.2 firmware but when I put my SIM card in (for T-Mobile) it doesnt recognize the network and I cannot place phone calls. Am I missing something?

    Im guessing one of the problems is that the phone has modem firmware 04.05.04_G. Is there a way I can change this so that I can use this phone?

    Or, am I screwed?

  10. Have same issue wiyh 04.05.04_G … did all … went fine… but when inserting SIM, it is constantly searching…

    Any sugestions??? PLEASE

    • I had the same problem…. iphone 2G 3.1.2. I fixed it by doing a Restore using itunes (after the blackra1n jailbreak) and then I did another jailbreak….it’s all good now. Phone works. I can turn on and off my phone. If the restore doesn’t work at first, download bootneuter with Rock, do a flash 4.6 and then itunes restore. Good luck.

  11. You all need to read things before updating…..

    Warning: The current update of Blackra1n only supports iPhone OS 3.1.2, do NOT use this tool if you are using an earlier version of iPhone OS. We have unconfirmed reports that BlackRa1n supports iPhone OS 3.1 as well, but we are not sure.

  23. If you have a 3GS Apple unlocked and running on 3.1.2, please do not jail break wih black rain. It screwed up my phone and I had to restore.

  24. i downloaded blackrain it told me to wait for rebot then my touch shut off itunes said to restore before i can use it wat do i do?

  25. i downloaded the program and tried installing it to my ipod touch 3.1.2 firmware and now it wont work it stays on the itunes plugin screen…. help me please =(

  26. if you have the ipod touch 3g or i think iphone 3gs you just have to rerun blackra1n whenever you fully turn off your ipod. That is what I have to do with mine and you will still have all of your apps including cydia

  27. Dont worry Delia, you can restore it and then again run same program, sometimes it just takes two or three tries. @thatguy – as the apple has upgraded the baseband of new devices we all have to rerun black rain; this is called as tethered jailbreak.

    Is it possible to install a jailbreak on my iphone 3gs 3.1.3 with new bootloader rom? If yes, please contact me.
    Best regards Andreas

  48. This is the best took bout 5-6 minutes.
    For those opf you who have jailbroken ur iphone and updated it from itunes will sometimes not be able to enter recovery mode to restore ur iphone. To fix this just start blackra1n and when ur iphone shows the restore thing unplug it and close blackra1n. then use itunes to restore and blackra1n to make it universally fuckable!

  49. hi ive tried to download the blackra1n but every time i open it or save it it says its missing the assdl or something like that or it has this little menu pop up and it says debug send error report or dont send ive tried blackra1n before and it went in recovery mode nut then it said to restore so i did and nothing happened so today i tried to restore and then do it and now i wont even open it just says its missing the assdll or whatever please help i just got the new 4.0 software

  50. Used blackra1n to jailbreak my 3.1.2 phone. Works good except can’t let phone batt die or turn off. Now phone is stuck in recovery + won’t restore. tried re-running blackra1n but it never finishes reboot. Can’t get the restore to work says the update is not valid? Can any1 help?

  51. hey i tried to download blackra1n and install it but it keeps saying im missing ASL.dll and wont open properly and when i click OK and push the “make it rain button” the program stops workin.

    can anybody help me with a simple answer

  52. Reply for T3Z4 and others facing the same issue.

    Apple has released a new version of iTunes, iTunes 9.1 which changes how certain things work. If you have upgraded to iTunes 9.1, several programs will start giving you an error that ASL.dll is missing.

    The solution for this is simple, you will need to place the Blackra1n executables in the Apple folder under Common Files in Program Files. The folder would be located in the following locations:

    32 Bit – C:\Program Files\Common Files\Apple\Apple Application Support

    64 Bit – C:\Program Files (x86)\Common Files\Apple\Apple Application Support

    Once you copy the blackra1n executable to the above folder, create a shortcut for it on the desktop and double-click it to run it as usual.

    Update: If you continue having problems with Blackra1n, you can use the new Spirit tool to jailbreak iPhone OS 3.1.3 and others.
