The Fuzzyband Baseband downgrader has been updated to 3.1b1 and now supports iPhone OS 3.0. It also adds an upgrade feature for those looking to use the ultrasn0w unlock.

FEATURES:
Upgrades / Downgrades baseband to 4.26.08 for unlocking with the ultrasn0w tool released by the iPhone Dev-Team

UPGRADING:
Upgrading is for users that wish to remain on 2.2.1 but also unlock. Upgrading will put the 4.26.08 baseband from 3.0 on the modem so that ultrasn0w may be installed from cydia

DOWNGRADING:
Downgrading works from any version greater than 4.26.08 (currently 5.08.01 is the newest version available, found in 3.1 beta 1). It will put your baseband back at version 4.26.08 which is the current unlockable version by ultrasn0w.

Downgrading only works on phones that have the 05.08 (5.8) Bootloader from the factory. This is a very limited number of phones that were released in the first few weeks of the 3G production cycle.

If you do not know your bootloader then you can run Fuzzyband and it will report the version number for you.

can it also downgrade a iphone 3gs which comes with a 3.1 firmware? The thing is that iphone 3GS will get released here in Denmark on 31 juli. And i am affraid if it comes with 3.1 firmware which i dont want, cause i want jailbreak. Will this software let me downgrade the baseband to 3.0 version??

This is for the 3G that first came out in 2008, not the more recently manufactured 3G or the 3GS.

If the iPhone 3GS truly hits Denmark on July 31, you will not have to worry about firmware 3.1. It would be a miracle to ship with 3.1 when it is still currently in beta. They have probably already manufactured the phones that will hit the European market and if not, they will most likely miss the deadline. Regards, -elc.
