Queste sono le istruzioni per fare l'unlock dell'iPhone 3G e del nuovo iPhone 3GS per usarli con le sim di qualsiasi operatore. Si procede utilizzando UltraSnow.

Prima di procedere con la guida, sincerati di avere un iPhone a cui è già stato fatto il jailbreak; è necessario avere baseband versione 04.26.08: ciò significa che è necessario avere il firmware 3.0 ed il telefono deve essere stato sbloccato con PwnageTool o RedSn0w.

Per trovare la tua versione di firmware e di baseband, si può seguire questo
this tutorial. Se non hai baseband versione 04.26.08, segui una di queste guide prima di fare l'unlock: Mac, Windows

Se hai T-Mobile come operatore, ricordati di spegnere il 3G (umts) prima di iniziare

Passo 1
Premi il tasto Cydia per lanciare Cydia Installer dalla tua SpringBoard.

Passo 13
Quando l'installazione è finita premi sul tasto grande Return to Cydia.

I finally made it on an iPhone 3G, 4.2.1, 5.15.04!!! Thanx for the tutorials, although they contain only bits of information, and if you get stuck anywhere you'll have to google further. To succeed, I used redsn0w v. 0.9.14b2, not the latest one (the latest one will give you faulty baseband after downgrade with no wi-fi, bluetooth or IMEI, and you will have to start all over again). After upgrading the baseband to 6.15.00, I got stuck on apple logo (bricked phone). To bypass this, you need to download, and Select IPSW iOS 4.1 (not 4.2.1), and use "Just boot" option. After the phone boots, it will be buggy (the screen), but it will become alive again. Check if the baseband is 6.15.00. If yes, proceed to Jailbreak in redsn0w (this time using 4.2.1 IPSW), and tick the boxes Install Cydia, and Downgrade baseband. After it is done, you will have an iPhone with baseband 5.13.04, which you can unlock with ultrasn0w, but (most probably) with "No service" bug. To resolve this, follow the tutorial concerning this matter, and voila! iPhone unlocked. This procedure felt like walking through thick bushes...

iPhone 3GS Version: 6.1.6 Modem firmware: 06.15 Install cydia ultrasn0w install finish... No service... How? Please help?

nomad - March 7, 2014 at 9:13pm

uninstall ultrasn0w, use redsn0w to downgrade from ipad baseband, that should bring you to baseband 5.13.0 or something like that, then install ultrasn0w again, good luck

nomad - March 8, 2014 at 11:13pm

correction : that should bring you to baseband 5.13.04 , i just tried it today

yrubin07 - April 29, 2014 at 7:42am

@nomad I tried downgrading and it gets stuck on the white text on screen part doesn't even get to flashing baseband

That worked for me on 3GS 6.1.6. From the beginning if I remember correctly, 1. redsn0w: uncheck Cydia and everything else, check upgrade to ipad baseband 2. Repeat redsn0w, this time with: check Cydia, check downgrade baseband. Now you have tethered boot 3. In redsn0w: Just boot 3. From Cydia, install p0sixspwn. This makes it untethered boot. 4. From Cydia, add the ultrasn0w repository and then install ultrasn0w. Voila! Service! For me the key step was to start over, then upgrade baseband first and then downgrade baseband. Finally recognized T-mobile sim.

Hey guys, want to unlock ATT devices? You can check out ATTiphoneunlocking, its the site i have been using for years to unlock my phone, it works pretty good

Thomas - March 1, 2014 at 10:44pm

Just did the jailbreak on my 3G using the iClarified instructions, and included the iPad baseband when I did it. Worked fine, now jailbroken, and shows 06.15.00... but, when I try to run the above, when I click to install Ultrasn0w, I get "the requested modifications cannot be applied due to...' :S

my iphone 4 basband is 4.12 how to downgrade to 4.10 ? 1.59 ?

daoshi - January 27, 2014 at 6:10am

I have an iPhone 4s with iOS 7.0.4, I cannot down grade to 6.x or 5.x. After I tried the steps suggested, it comes with a message "SIM Not Valid". Anyone suggestion, ot it just doesn't work for 7.0.4? Thanks. Joseph

Duardinho - January 25, 2014 at 5:40pm

Hi all! I've just jailbreaked my iphone and now tried to unlock it because I changed carrier... now, it keeps searching for the carrier and I cannot make any calls... any suggestion? I'm a bit "fresh" on this kind of matters. Thanks all

jag broncano - January 21, 2014 at 5:57am

Thanks you so much..

Jimmy - January 14, 2014 at 5:48pm

Worked at last. Thanks guys. Downgrading my baseband from 6.15 to 5.13.04 did the trick. I have 3Gs and updated it to 6.1.3. with iTunes, JB with redsnow, install Cydia, Ultrasnow, then p0sixspwn for untethered JB. Found everything OK, except it was still SIM locked. Did the baseband downgrade with Redsnow and right away I could call out. Thanks again.

Gaurav - January 11, 2014 at 8:44am

Thanks Iclarified. I got my phone unlocked. Now can i update my phone to ios 6.1.3 (currently on 4.1.1) without getting my phone locked again ?
