3G Fuzzyband ^[1] Downgrader is now available in Сydia. This should be used instead of 3G Baseband Downgrader ^[2] for downgrading the baseband ^[3] on phones containing the 5.8 bootloader ^[4].

Benefits over original downgrader:

• Does version checking, will only downgrade if phone is eligible
• Downgrades all versions of baseband from 2.30.03 to 4.26.08 (3.0 beta5)
• Reports current bootloader version on screen

The original downgrader was a possibly dangerous app, as it relied on a failed downgrade to decide whether downgrading was possible. Anytime you run BBUpdaterExtreme you are potentially doing damage to the modem, so the version checking in this app minimizes the chances of accidently corrupting the baseband.
