Estas son las instrucciones de como hacer el "downgrade" de tu baseband a 2.28 para iPhone 3Gs que tienen el bootloader 5.8 usando Fuzzyband. Esto te ayudará a que puedas desbloquear tu iPhone 3G usando YellowSn0w.
Fuzzyband es la aplicación preferida para hacer el downgrade de tu baseband, ya que verifica la versión, y hace downgrades de todas las versiones del baseband, desde 2.30.03 hasta 4.26.08 (3.0 beta5), y además te reporta la versión actual del bootloader en la pantalla.
Paso Uno Presiona el icono de Cydia desde tu Pantalla (springboard)
Paso Dos Presiona para seleccionar el tabulador de Section en la parte de abajo de la pantalla.
Paso Tres Presiona para seleccionar System de la lista de secciones
Paso Cuatro Presiona para seleccionar 3G Fuzzyband Downgrader de la lista de aplicaciones
Paso Cinco Presiona el botón de Install en la esquina derecha superior de la pantalla.
Paso Seis Presiona el botón de Confirm en la esquina superior derecha para empezar la instalación.
Paso Siete Una vez que la instalación termine exitosamente, preciona el botón grande de Return to Cydia.
[bPaso Ocho/b] Presiona el botón Home para regresar al SpringBoard. Verás una nueva aplicación que se llama Fuzzyband. Presiónala para iniciar la aplicación.
Paso Nueve Inmediatamente después de activar la aplicación, se te mostrara un mensaje que Fuzzyband esta investigando tu modem.
Una vez que termine, se desplegará la versión del Bootloader, la versión de tu Baseband and la versión del OS de tu iPhone.
Si tienes una version de bootloader superior a 5.08 entonces no podrás hacer el downgrade de tu baseband y un mensaje de Not Supported (no es soportado) se desplegará.
Si tienes el bootloader 5.08, entonces podrás hacer el downgrade de tu baseband 2.30 o superior. Presiona el botón de Downgrade para iniciar el downgrade de tu baseband.
Paso Diez Una vez que el downgrade a terminado exitosamente, se desplegará un mensaje Done!, "I Haz Downgrade!" y ya estarás en el baseband 2.28.

Please let me know if we can degrade the baseband version with bootloader version 05.09 or how do we degrade the bootloader version to 05.08. Please help me !!!!!!!! email - shashi.net@gmail.com
Hi there. my Bootloader Version is 05.08 [G2M3S2] according to the Fuzzyband Downgrader but it says it's not supported because of my Baseband Version. Is there any solution ? Here's the info on the screen:
BootLoader Version: 05.08 G2M3S2]
Basebadn Version: ICE2-02.28.00
iPhone OS Version: 2.2.1
Thank you for your help.
Hey there, my iphoned is jailbroken, I have Cydia that's how I used the Fuzzyband Downgrader. But it just says it's not possible. I guess it's the Baseband and not the BootLoader. Here is the info again:
BootLoader Version: 05.08 G2M3S2] Baseband Version: ICE2-02.28.00 iPhone OS Version: 2.2.1 Thank you for your help.

Help contact thanking you
It is balance Garden but yet, it is not in the solution.
I downloaded the BownBB, Fuzzyband file and RUNed pula Gramm.
It is sorry but because the bootloader is 5.9 version, the SIM lock can not be canceled.
Once again, we request in the help.
It says clearly in the post that "If you have a bootloader version higher then 5.08 you will not be able to downgrade your baseband and a Not Supported message will be displayed." What do you think?
SO I DID IT ON MY IPHONE AND IT WORKED I GOT MY IPHONE BACK FROM 2.30.03 TO 2.38.00 , BUT MY QUESTION IS WHEN THE NEW 3.0 FINAL RELEASE COMES OUT AND IF I UPGRADE WILL THIS UTILITY WORK AS WELL AS LONG AS I HAVE THE 5.8 BOOTLOADER? WELL AS LONG AS MY PHONE IS JAILBROKEN.
Hey ricardo, just wanted to know when you upgraded your phone to baseband 2.30 did your wifi stop working or was it ok. because i when i upgraded my wifi stoped working so i wanted to know if yours start working again after you downgraded
Thank you for the help.!
However, yet, the problem could not be solved.
Again, we request your help.
At present, it is " modem version 02.30.03 ", "OS 5G77".
Tell the way of changing into modem version 02.28.0.
It tried a down grade in the envoy modem version in the Fuzzyband software.
However, because the bootloader version was to do 5.9 being, it isn't possible to do a change.
Tell the way of changing a bootloader version into 5.8.
Or, tell the way of modem version's being able to be changed in the other way.
I request your help.
Thanks guys, great job i manage to jail break my iphone 3g 2.2.1 but unfortunately my bootloader is 5.9.
I am convince there will be a solution for this, please help.
Thanks again.
what i dont understand is that if this app is available thru CYDIA then the iPhone 3g must already be jailbroken to download it. so why wud someone need to downgrade an already jailbroken phone.
Does it make any sense?
Hi
I've tried to downgrade my phone with Fussyband it turns out I've got 5.9.
My question is if I was to down grade the firmware to 2.2 would that give me a down graded baseband?
Regards
If you have an iPhone 3G (firmware 2.2.1, baseband 2.30.03, bootloader 5.08) and it's locked, but you want it unlocked, you'll need to install Fuzzyband.
