Unlock iPhone 4 On iOS 6

iOS 6 brings a new baseband that is a what you might called it a minor-update for the unlock as the baseband is now 4.12.02. Well folks those of you who had saved the SAM unlock activation tickets are in for a luck as you can unlock your iPhone running on iOS 6.

SAM unlock activation tickets are the key for unlocking any iPhone no matter which baseband or which firmware it is running on. So let’s take a look on how to unlock iPhone 4 baseband 4.12.02 on iOS 6.

Unlock iPhone iOS 6 Using SAM Unlock

At first I had my doubts whether these activation tickets will work on iOS 6 or not but as it has turned out they do in fact unlock iPhone on the latest firmware from Apple.

I talked to a couple of people who had success in unlocking their iPhone and they mentioned it to me that the process was the same as before. The same restoring process which we had a guide about quite a long time ago.

So I used unlock activation tickets to unlock an iPhone running on iOS 6 and Voila! The iPhone 4 was unlocked on iOS 6 using the SAM activation tickets.

The title mentions “unlock iPhone 4…” because I tried this method on an iPhone 4 and it worked. Those of you who have iPhone 4S can use the exact method to unlock your iPhone using the saved activation tickets.

Procedure To Unlock iOS 6

  1. can i update my iPhone 4 to IOS 6 and then backup my SAM unlock with redsnow without making the Jailbreak ?? ….because this Jailbreak is not stable and i think there will more versions of redsnow to fix the jailbreak for IOS 6
    and at all i prefer to wait the version of redsnow or Snowbreeze that grants the preserving of baseband of the firmware IOS 6 to be more protected from upgrading my baseband

    • During the redsnow jailbreak process you can just install activation ticket and untick the install openSSH as redsnow right now won’t install cydia.

  2. This worked great, updated my iPhone 4 to iOS6 using redsnow and installed the activation ticket during the jailbreak process and it worked like a charm.

    this worked as great as i never expected …. iphone4 now with ios6 jailbreaked and restored the SAM Ticket while jailbreaking ,,,, thanks :)

  4. I have saved the ticked at 24.4.2012, some days after unlocking my iphone 4 (4.11.08). I am not sure if it would be valid when I will install on iOS 6.

  5. DO NOT tryxto do this using Cookie to back up and restore your activation ticket. I lost my SAM unlock when the only wi-fi available ( I’m in a rather remote area of the world, so I’m stuck with one wi-fi access) would not allow the ssh to go through. Without Cydia or ssh, no Cookie and therefore no activation ticket.

    On another subject, the unlock from officialiphoneunlock.co.uk worked like a charm. The only downside is that this unlock is missing the coolness-geeky factor and thriftiness of the SAM unlock.


  7. Hello,
    I am on Iphone 4, 4.11.08.
    SO FARHAN, i have 2 queries if u can answer i will be more than happy. :)

    1. Is the Jailbreak is functioning fully on iOS6.
    2. IMP. : I have SAM unlock, but i did not save the activation ticket. Can i save the activation ticket now ??? And than update to IOS6. Means the activation ticket would work now or not? If i back it up today?

  8. Just unlock the “old” iPhone 4 (all basebands), damn the iPhone 5 is out and iPhone 4 is still locked… What a shame… It´s like having a car without steering wheel…

  9. Maybe someone can help me with this question. I need to unlock my iPhone 4. It has already been jailbroken with redsnOw. Current Version: 6.0 (10A403) - Modem Firmware: 04.12.02. I tried these steps above and when I insert the sim for the carrier that I want to unlock it for it says…Invalid Sim. So I guess it did not work :-(

  10. You can unlock any AT&T iPhone to use on T-Mobiles network. I am currently with T-Mobile paying a great monthly rate on a iPhone 4s that was originally locked to AT&T’s network. I got my IMEI# based iPhone factory unlocked from the friendly people at: iphonefort-mobile.com I was notified that the unlock was complete in a matter of hours. I paid $40.00 and am very happy that my phone is now unlocked. I also traveled internationally with it.

  11. i have an iPhone 4 at the baseband 4.10.01
    if i upgrade to iOS6 using custom firmware to preserve baseband, will it be unlocked with my backup sam ticket ?
    Or even if i upgrade to the new baseband, will it work ?
