Considering that the ultrasn0w version compatible with iOS 4.3.1 was released this morning, I think that some of you would like to know how to unlock your phones. We are of course talking about iPhone terminals that have an old baseband, that is, up to 05.13.x in the case of the iPhone 3GS and 01.59.00 in the case of the iPhone 4. For basebands with a higher value, there is no solution for unlocking at the moment and it is not known whether ever exist If you still have such a baseband, then you can try a Gevey 3G or Rebel Micro-SIM decoding card.
Using this tutorial you will be able to unlock for:
- iPhone 3GS baseband – 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00;
- iPhone 4 baseband – 01.59.00.
iPhone 3G is not compatible with iOS 4.3.1. To check your baseband go to: Settings>General>About and modem firmware you will see what version you have. Now let's see what are the steps to be taken to decode an iPhone 4.
Step 1
Update to iOS 4.3.1 using Pwnagetool on Mac OS X, sn0wbreeze on Windows or TinyUmbrella(iPhone 4 only).
Step 2
Now that you have iOS 4.3.1 jailbroken on your terminal, it's time to install ultrasn0w which does the decoding. Open Cydia and press the fourth button at the bottom of the screen, then choose the category Sources.
Step 3
Select the repo repo666.ultrasn0w.com and you will see the ultrasn0w package available for installation.
Step 4
Select the ultrasn0w package, then press the Install button on the top right, then the confirm button.
After installation you will be asked to reset the terminal. Press the reboot button and upon restarting you should have a signal.
It also had signal, 1 line, with ultrasn0w fixer by ih8sn0w, but with the new update of ultrasn0w it is full.
misleading headline :-w
I was sure you were going to say that, but it's not misleading at all. Those who have an old baseband can unlock, those who don't, no.
It was misleading if it said "any" iPhone.
I have a 3gs with ipad bb, 06.15.00. If I update the bb, can I use the GPS? I put 4.3.1, jailbreak, unlock and try to see if it works.
thanks
You cannot update the baseband. You can't use GPS.
hello zaone, I have an iphone 3gs with 3.1.2 and bb 05.15.04, any chance to unlock it somehow? to downgrade or smth?!
What is written in the tutorial?
Hello Zaone... I'm confused at the beginning of the thread it says that it is possible only at bb lower than 6.15 on 3gs, but after half it says that it is possible at 6.15... so is it possible or not?
Ms
Lollipop 🙂 ..look at step no. 4 and if you have a BB there that appears in the image you can decode it 😉 !
zaone, usually with ultrasnow the battery consumption is high, do you know if they did something in this sense with this update 1.2.1
Perfect! Let's see how it will be, as I tried, the GPS works!
ultrasn0w uses mobile substrate / one of the answers for battery autonomy.
I upgraded to 4.3.1, yes, I unlocked it, but the data traffic no longer works, I also used the "Iphone configuration utility" utility and still in vain. Iphone4 (01.59.00) on rds. Has anyone else had this problem?
yes I [solved] it happens when your phone is coded, you hack and unlock with ultrasn0w, you can't do the data / 3G settings and it doesn't work with the profile in iphone config utility either. (yahoo ID like here)
I will make an article about it.
Sal Zaone! I have a 3gs 4.0,BB 05.13.04. So far, everything is fine and dandy, I installed ultrasnow for decoding, orange and cosmote work for me, but no service appears on vodafone with a smaller card. What could be the problem? Thank you.
Hmm, it's the first time I've heard of such problems, have you tried resetting the terminal?
Yes, I reset the network, then I noticed that in Gen/Inf/Network: it appears unavailable and when I go there it says, Sim not supplied. Ms reply so fast!
I solved. It was the blame card :D. Thank you once again
I have some doubts about the update. I bought a phone (iPhone 3Gs) with ios 4.0 jailbroken and unlocked. If I update to version 4.3.1 with sn0wbreeze, will it restore my file system from scratch and I will lose all installed programs? The current size of the system partition is 750M, and the minimum allowed by sn0wbreeze is 850M.
, you will lose everything.
I have a 3Gs 16gb, 4.1(8B117) BB 06.15.00 Please tell me if it is worth updating to 4.3.1 and if there are any disadvantages, please tell me the most important ones...I specify that now not My GPS works and this annoys me to the max, is it possible that updating it will work?
hello zone, I have an i4 bb 04.10.01 version 4.3.1 .. can I unlock it? Have a good evening
Only with Gevey 3G.
I unlocked after this tutorial on Iphone 3Gs 3.1.3 05.12.01 and now I have a black screen, how can I restore it?
Press the home + lock buttons simultaneously and hold them until it opens.
