If you don’t have a sim card to activate your iPhone and you need to skip this screen then follow the step by step video below to get your iPhone up and running in no time.  This tutorial works on all version from iOS3 all to way to iOS6!  Note: In the video, the activation screen my iPhone 3G has will probably be different than from what you have.  Apple changed the activation screen in iOS5 and iOS6, however, this tutorial works for all iOS versions mentioned.  You need to download the two files below.  If you don’t know what version your iPhone is on, watch the video and it will tell you.

    Thanks to you dude I just activated my Iphone 3g.
    I have the same problem in the last part of your video.
    After activating it there is no service.
    Have you made a video fixing that problem? Cause the only video i see is for Iphone 3gs

    Hey! I just used this video to jailbreak my iphone 3g with firmware 4.2.1, but afterwards i’ve got the problem “no signal/searching” How do i fix that problem with firmware 4.2.1?

  47. Lucia says:

    Hi. I have iphone 3g. I followed every steps, downloaded everything it needs to activate my phone, however, when I got to the last part where the redsnow will/should do its magic, I got stuck holding the home button for nearly 30 minutes since the progress bar isn’t moving or the itunes didn’t pop up.. then out of the sudden, my phone just shutdown. I kept pressing the home button still for another 30 minutes but nothing happened. What should I do? Has this something to do with the fact that I just fixed my phone first from error 1015?

  48. Filip says:


    I did everything, acc video, but when I turn on my 3gs, is still asking me for activation and then is write me that activation server is not wotking or something like that, so I can´t evet switch on. what shoul I do?

    HELPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE!
    I have an iphone 4 on ios 6.1.3 and i did everything on your video and it still is bringing me back to the activation screen! someone please help!

  50. Hiten M says:

    I have iPhone 3G (4.2.1 – 5.15.00). I followed the same steps using redSnow 9.15.b3 and IPSW “iPhone1,2_4.2.1_8C148_Restore.ipsw” but it brought me back to same screen of activation.
    I never get ‘Next/Finish’ button on redsnow. Plus, my iphone screen does not show any log or activity unlike in the video your screen shows lot of activities at the time of jailbreaking.

    • Louis says:

      hey Hiten,
      after you selected your IPSW, did you click back and than hit jailbreak? After it is done jailbreaking it will automatically bring you to a screen where it says put your iphone into DFU mode after you power of your iphone it will bring you to a screen of insctructions on how to put it into DFU mode. after all this is done all that writing you said that didnt show up, should come up this time. I have the same problem it brings me back to the activation screen after i followed the same exact steps like 10 times! hope this helps Hiten
