    Hi there i have Iphone 3GS 32gb, with modem firmware 04.26.08. version 3.1, is it possible to JB and unlock the phone with this balcksnow?

  • Brian

    Loos very similar to the BR1 and BR2 issues.

    We have many stating it worked great with no problems (congrats to those people!!)….but I am seeing just as many people posting the same stuff that was posted about BR1and 2.

    “I’ve tried everything. Followed instructions to the letter..tried different tricks but this or that is not working..HELP….Device is bricked…HELP…Device stuck in DFU mode..HELP…Device wont reboot….HELP..” and etc, etc….

    Once again, congrats to those it worked for and I sincerely hope it continues to work.

    I will dive in to the code this weekend to try to see what is in there as well as trying to find whatever holes there are that for whatever reason, makes it work for some, but not for others, leaving MANY with a perfectly working unlocked/jb’d device and MANY others with a bricked device.

    Also, please be aware that at any time APPLE will have coding that will recognize a ‘modified’ device so I would be very careful when plugging in to itunes.

    To whoever installed Winterboard, and now has their iPhone on unlimited reboot. Don’t worry, the reason that happens is because everytime you reboot, you need to run BlackRa1n.

    Connect it to ur USB, run blackra1n rc3, keep it running. Let it reboot forever, and suddenly you will see your screen change to Steve Jobs image, and the Geo Hotz pic comes up. After that your iPhone is jailbroken again, and now you are good to go.

  • Justin

    @ Brian
    Uh Apple nor any company are allowed to create a code that allows them to see what apps are installed or whether or not the iPhone is modified (which requires checking everything on the iPhone cause jailbreaking installs a few components integrated into the iPhone OS)

    That would be somewhat like trespassing… reviewing what you have which is pretty much illegal unless you approve it (which I won’t lol)

    They can detect whether a firmware is genuine or not though (if you update to 3.0 OS without paying for it on a iPod touch, you’ll have to disconnect from the internet every time you sync)

  • David

    Brain you do realize that those people who claim their device is bricked might just not know what they are doing right?

  • benk2

    Thanks GeoHot
    U’r the Best
    I will donate $$ for u.
    Thanks again

  • Gia

    I’m not sure if anyone else out there is having this problem, but I seem unable to find Blacksn0w in Cydia. Any suggestions? I already jailbroke my iPhone 3Gs (without sn0w) and would like to enable the tethering. Thanks for any help with matter.

  • Soren1974

  • Suresh

    after installing blacksn0w. when complete screen pops up then my iphone got hang for few minutes and then automatically it restarts and stucks in apple logo …..what can i do now…plz help?

  • Lewis

    Hi , i have the same problem stuck after install in Apple logo, any ideas please??

  • tony_1

    eyy man i have the same problem what you do to fix that problem

  • Nigga

    same problem as the above three. its because our phones are updated past the firmware that blacksn0w works on. you have to put your phone back in dfu mode and reboot it to the original firmware
