****THIS TUTORIAL HAS BEEN UPDATED FOR THE NEW ULTRASN0W UNLOCK THAT WORKS ON THE 3.0 FIRMWARE. IF YOU ARE ON THE 2.2 FIRMWARE THIS TUTORIAL WILL STILL WORK; HOWEVER WE RECOMMEND YOU UPDATE TO 3.0 AND FOLLOW THESE INSTRUCTIONS****

These are instructions on how to software unlock the iPhone 3G for use with any GSM cellphone carrier.

Before you can follow these instructions you must have a jailbroken iPhone and you must be on the 02.28.00 baseband(modem firmware). This means that you must be running the 2.2 firmware or have used PwnageTool(NOT QUICKPWN) to install 2.2.1 without upgrading the baseband.


To find your firmware and modem firmware(baseband) versions you can follow this tutorial. If you are not on baseband version 02.28.00 then you need to follow one of these tutorials before unlocking: Mac, Windows


For your convenience this tutorial is available in video format also.

Step One
Press to launch Cydia Installer from your SpringBoard.

Step Fifteen
You should now be able to insert the SIM of your choice!

***HINTS: It seems that getting your iPhone to pick up your new carrier can be helped by turning off 3G and perhaps toggling the Airplane Mode switch on and off. If you are still having problems try removing and reinserting the SIM or booting with the new SIM already inside. Finally, you can also try to Reset Network Settings from the Settings:General:Reset Menu.

***IMPORTANT: For those having trouble. The yellowsn0w application can simply be uninstalled. If you have tried all the hints and suggestions and still have problems just use Cydia to remove the package and then reboot. You will then have service with your locked carrier as always.

***THANKS: A big thank you to all the members of the iPhone Dev-Team for all their hard work! It is much appreciated by all.

***UPDATES: The Dev-Team has made yellowsn0w 0.97 available. This version supports the 2.2.1 firmware using the 02.28 baseband.

I jailbroke and unlocked my 3G to use on the T-Mobile network and it is working fine. The only thing is that prior to jailbreaking and unlocking it, you were able to send pictures in text messages. Once I unlocked it however, the icon button to "add a picture" into the message no longer appears. Anyone have any ideas? Any help would be much appreciated! Thanks is advance!

Hi, I´m trying to jailbrak my Iphone 3Gbut I can´t download (under source) apt9.yellowsn0w.com. The message it gives: Sub-process /bin/bzip2 returned an error code (2) FW 2.2 is installed. I also have restarted the phone several times, but no change. Is it possible that the provider (Tmobile) has to do something with the problem? What can I do to solve this problem? Do you have any idea or alternatives..? thanks! Hallo, bin gerade dabei mein Iphone 3G zu jailbreaken kann aber mit Cydia unter Hinzufügung der Quelle: apt9.yellowsn0w.com die datei nicht runterladen. Anmerkung: Sub-process /bin/bzip2 returned an error code (2) FW 2.2 ist drauf. Hab auch mehrmals neugestartet und immer nach Anleitung vorgegangen. Kann es am Netzanbieter (Tmobile) liegen? Was kann ich machen um das Iphone freituschalten? Habt ihr ne Lösung, abdere Alternativen? Vilen Dank.
