Aquí están las instrucciones de cómo liberar el iPhone 3G para usarlo con cualquier operador telefónico.

Antes de seguir las instrucciones necesitas tener un iPhone con 'jailbreak' y debes tener la versión de baseband 02.28.00 (modem firmware). Esto significa que necesitas tener el firmware 2.2 en tu iPhone o haber usado PwnageTool (NO QUICKPWN) para instalar la 2.2.1 sin actualizar la baseband.

Para saber que versiones de firmware y modem firmware (baseband) tienes puedes seguir este tutorial. Si no tienes la versión 02.28.00 de baseband entonces necesitas seguir uno de estos tutoriales antes de liberarlo: Mac, Windows

Paso Uno
Presiona para ejecutar Cydia Installer en tu SpringBoard.

Paso Dos
Presiona Manage en la parte inferior de la pantalla.

Paso Tres
Presiona el botón grande de Sources.

Paso Cuatro
Presiona el botón Edit en la parte superior derecha de la pantalla.

Paso Cinco
Presiona el botón Add en la parte superior izquierda de la pantalla.

Paso Seis
Introduce http://apt9.yellowsn0w.com/ como 'source url' y presiona el botón Add Source.

Paso Siete
Cuando la 'source' haya sido introducida presiona el botón grande de Return to Cydia.

Paso Ocho
Presiona el botón Done en la parte superior derecha.

Paso Nueve
Presiona apt9.yellowsn0w.com de la lista de 'sources' introducidas por el usuario.

Paso Diez
Presiona yellowsn0w de la lista de paquetes.

Paso Once
Presiona el botón Install en la parte superior derecha de la pantalla.

Paso Doce
Presiona el botón Confirm en la parte superior derecha de la pantalla.

Paso Trece
Cuando la instalación haya terminado correctamente presiona el botón grande Return to Cydia.

Paso Catorce
Ahora aprieta el botón Home , apaga el iPhone y vuelve a encenderlo. Para hacer esto mantén apretado el botón de encendido 3 segundos y desliza el 'slider' que aparece hacia la derecha. Aprieta nuevamente el botón de encendido para encender el iPhone.

Paso Quince
¡Ahora deberías de poder introducir la tarjeta SIM que prefieras!

***CONSEJOS: Parece ser que si apagas el 3G y supuestamente encendiendo y apagando el modo avión ayuda a tu iPhone a coger la nueva operadora. Si sigues teniendo problemas prueba a quitar y volver a meter la SIM o encender el iPhone con la nueva SIM ya dentro. Finalmente puedes probar a resetear los ajustes de red en Ajustes->General->Restaurar

***IMPORTANTE: Para los que tengais problemas. La aplicación yellowsn0w puede ser simplemente desinstalada. Si has probado todos los consejos y sigues teniendo problemas simplemente usa Cydia para eliminar el paquete y después reinicia. Tendrás servicio entonces con tu operadora sin liberar como siempre..

***AGRADECIMIENTOS: ¡Gracias a todos los miembros del iPhone Dev-Team por todo su duro trabajo! Todos estamos muy agradecidos

***ACTUALIZACIONES: El Dev-Team ha sacado yellowsn0w versión 0.97. Esta versión es compatible con el firmware 2.2.1 usando la baseband 02.28

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!

For me changing providers was easy. In Canada there are two providers that have the iPhone Fido and Rogers. I had a Fido iPhone. When I switched my provider to Rogers my iPhone would not work with my new sim card. So I put the Rogers sim in my iPhone and went to the Apple store. I told them that that battery in my phone wasn't working right. They just replaced the whole phone and because they thought it was a Rogers phone because of the sim card I now have a working Rogers iPhone. No unlock required.

Hey Folks, I have an Iphone 3g version 2.2.1 firmware 2.30.03 and a bootversion 5.08 I succesfully jailbreaked and succesfully downgraded the baseband to 2.28.00 Then I installed yellowsn0w to unlock and... it's still locked... have tried it 3 times from beginning to end now, not knowing what I did wrong... anyway my main issue is that my original T-Mobile sim card doesn't work anymore neither! so it's nothing more than a IPod Touch right now... please help!

If your not bothered about unlock can't you restore from backup

irvk - April 29, 2009 at 8:02am

I'm new to this. I have both mac & windows vista &iphone 3g. What is the status to jailbreak & unlock with the latest firmware? I'm confused on this & don't want to try anything in case I wreck up my phone. Is a card such as rebel sim better for me? Help!

I have a 2g iphone that was on 2.2.1 and I lowered it to 2.2. It has been jailbroken with quickpwn, and I also put the yellowsn0w app on with Cydia. After cydia installs it, I don't see any new icons. I've tried toggle airplane mode, reboot, etc. After switching to a TMOBILE SIM, THE PHONE BRICKS ITSELF AGAIN WANTING TO CONNECT TO ITUNES. Works fine with ATT sim card, has not detected any other simcard. Help!

jazz - April 23, 2009 at 1:33pm

As far as I can remember you don't need yellowsn0w with 2g I think you are following 3g guide.Do the jailbreak again but remember to tick activate box.You don't need to restore in iTunes b4 you redo the jailbreak make sure u use the 2g guide

Jazz - April 23, 2009 at 1:42pm

I did but Boo Neuter didn't run, any ideas as to why or how to force it?

JAZZ - April 23, 2009 at 1:47pm

I was able to get Boot to load this time around. However when the iphone comes back on I still get the same message of "Different SIM detected, please connect to itunes"

jazz - April 23, 2009 at 1:55pm

Are you doing the jailbreak with that sim card installed I think you should do. Try it anyway and remember to tick activate then if that fails start again from the beginning of the how to.
