Fuzzyband 3.1b1 Update Available In Cydia

July 9, 2009

A few months ago I posted about a tool we developed, called Fuzzyband, to downgrade the baseband on the 3G iPhone to make it unlockable again.  We've recently pushed out an update to that tool, though the feature set has changed a bit due to developments by the Dev-Team. 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.
