  1. Just re-jailbroke. Definitely worth it. Waited for blackra1n before I went to 3.1.2. It’s too bad apple won’t make some of these features native. Might be a big deciding factor when it’s time get a new phone.

  2. Hmm had so many issues with Version 1 of blackra1n I was skeptical about using this version….

    However I just used it and all seems to be working well.

    My iPhone was already upgraded to 3.1.2 with the 5.11.7 baseband.

    I left my phone on, connected it to my hp dv4 and then downloaded blackra1n.

    Then I clicked make it ra1n and voila. I didn’t have to run it in compatibility mode or even put it on my c-drive, I launched it straight from my downloads folder.

    In all it took about 45 sec…it went to the restore screen then to the screen with geohot. Stayed there about 30 seconds. The done, wait for phone to reboot screen popped up before it was finished.

    All seems to be working fine though.

  3. Hey guys,

    I jailbroke my iphone 3gs running on 3.1 (5.11.7) basebandwith the new blackrain. Does this mean that this is a tethered jailbreak and everytime my battery dies i will loose all the data inserted.

    Thank you,


  4. I connected my ipod touch 3rd gen (32gb) on 3.1.2 firmware, but when I press make it rain, it says “waiting for device” and nothing happens.

  5. i connected my i pod to i tune and installed 3.2.1 5.11.07 after that it is not working properly then i did to brake it from blakra1n after that carrier software is not working properly so how to re install the carrier software .also i try to battery shout down but same thing happens like before so pls give any idea expect blackra1n software.

  6. ive never used a i pod touch before so can someone tell me waht to do and i would gladly accept that plzzzz
    and what version does it have to be

  7. i am having iphone 2g with baseband 04.05.04 os 3.1 but when i tried to jailbreak my iphone it just unlocked but when i use iphonebrowser it shows that my iphone is not jailbroken any suggestion plz

  8. I tired to jailbreak my iphone and when I went to download a theme it put my phone in recovery mode!!!!! Y did it do this? I’ve been putting off jail breaking my iphone because I just knew something would go wrong!

  9. I don’t know about anyone else, but here’s what I did: I updated from 3.1 to 3.1.2 on 12-30-09. Then I downloaded blackra1n. I installed it, ran it, and clicked on “make it rain”. It worked like a charm. It even restored tethering for me that I lost when I upgraded to 3.1. The only thing that is annoying, is that iTunes keeps trying to alert me that it has a carrier profile update that needs to be installed. I rejected it because I’m afraid I’ll lose tethering or my jailbreak/unlock will be screwed up. I think it immediately fixed the tethering because I still had the profile installed that you download to make tethering work in 3.0 and 3.0.1. I didn’t have to do anything. Another thing that’s odd is that when I’m surfing the net while tethered, it doesn’t show up in Network under System Preferences on my mac. It works, but there’s nothing onscreen indicating that it’s working except for the fact that I can get online.

  10. I have a 3G Version 3.1.2 Firmware 05.11.07.
    Used Blackra1n with Cydia jailbreak and unlocked perfectly to my UK provider.
    Got MMS, Tethering using APN profile from
    Read somewhere that Blackra1n should be uninstalled after jailbreaking so I unistalled Blackra1n app, BUT Cydia disappeared along with it.
    I want to download other apps but without Cydia or similar how can I do that?
    I particularly want to edit the carrier.plist to get rid of that pesky “Call Forwarding Active – Dismiss” message
    Tried re-installing Blackra1n, but that just re-boots the phone now. I really do not want to restore the phone – is there another way to install Cydia please.

  11. Hi, Please help, I have succesfully install the blackrain icon in my iphone. However, when I tap on the icon in my iphone, I always get error message: “Please check your internet connection”. I was in the Wi-Fi enable and able to browse internet go to iTune from the iphone but whenever I tap on the balcrain icon, I always get that error message and I have not seen any Cydia, Rock or Sn0w applications at all… Please help! Thanks

  12. Kristen- Its likely that your iphone is a tethered jailbreak. Meaning everytime that the phone is powered off or the springboard restarted it will require to be plugged into PC and black rain run again. You will not lose anything that has been previously installed. Its best to not turn off ipod or iphone on a tethered jailbreak.
    But if you do ,no worry ,just plug in and make it rain(blackrain).
