Fuzzyband helps downgrade iPhone 3G 3.1.3 Baseband 05.12.01

Do you want to downgrade your updated iPhone 3G device? iPhone downgrader is here!

Fuzzyband Downgrader helps users downgrade their iPhone 3G baseband 05.12.01 to 04.26.08. Unfortunately, it is not supporting iPhone 3GS. So, iPhone 3GS users will have to wait for some other downgrader tool.

Fuzzyband Downgrader can be downloaded from ‘Cydia’. You just have to search Fuzzyband in Cydia to get this tool. After installing this downgrader on iPhone 3G, it will check the baseband and if it detects any problem, your phone’s baseband will be downgraded.

I don’t think there is a need for any guide to use Fuzzyband Downgrader tool. In case you find any issue, just leave a comment below.

Once you are done with downgrading process, check the following guide to unlock iPhone 3.1.3 firmware.

How to unlock iPhone 3.1.3 Firmware?

Note: Not all iPhone 3G phones work with Fuzzyband. You may find trouble with iPhone 3G too. I would recommend you to wait for Dev team tool.

if you update your phone 3.1.3 you can make jailbrak or you can go back to 3.1.2 version and you can make jailbreak too. but now your baseband (05.12.01) that why you cannot unlock it

By mistake I upgrade my IPhone 3g to the new version 3.1.3 and I lost the jailbrake and the unlock... But I followed this process and I could downgrade to the 3.1.2 and install blackra1n... I hope this will help you
