Fuzzyband just announced on their Twitter page that version 4.1 is out on Cydia. It confirms that it will downgrade baseband version 5.14.02 to 5.13.04 for Ultrasn0w.
However, this only works for bootloader version 5.08.
How to downgrade your baseband:
1. Launch Cydia from your springboard, and go to systems under section tab.
2. Press to select 3G Fuzzyband Downgrader from the list of packages and click on install.
3. After installation is completed successfully return to Cydia and press home button and launch Fuzzyband.
4. A message will be displayed if your bootloader is not supported, If you have the 5.08 bootloader you will be able to downgrade from baseband 05.14.02. Press the Downgrade button to begin downgrading your baseband.
5. Once the downgrade has completed successfully you will be displayed a Done! message saying, “I Haz Downgrade!”
Did this work for you, leave your comments below?
Do a hardware downgrade and unlock your iPhone! Read here.
So I’m trying this right now…. so far it gives me this message:
“This software cannot be used on iPhoneOS 3.0; You must downgrade to 2.2.1 or lower.
I’m gonna try downgrading, lets see how this goes.
@Lyssa: Good luck and let us know!
I am on T-Mobile network though, if I update will it allow me to activate without a proper SIM?
What are you using to restore?
I have my T-Mobile sim in. I'm using itunes
if your official carrier is T-mobile and you have an official T-mobile SIM, you should be able to activate it
i updated my phone into 4.1 and my baseband is 5.14.02 how to
unfortunately there's no unlock for baseband 5.14.02. We have to wait.
Any one no how long we have to wait
not more than 72 hours, I think?
I have never seen this happening, anyone can shed some lights on this?
I personally haven't tried 3g on 4.1 and BB 5.14.02
Has anyone tried it with iphone 3gs old bootrom 4.1 ??
Did you try installing it via Cydia? Won't do any harm…

Thank you!
you can only use fuzzyband if your bootloader is 5.08, you can install it with ICY if you have no WiFi, Google for it
If you search for fuzzyband then you can find the updated one.
