I have seen in the bellow link one can downgrade base band from 05.12.01 to 04.26.08 and unlock 3G ver 3.1.3 using program called fuzzyband. I have 3G iphone jailbroken and need unlock. baseband is 05.12.01 and need to install fuzzyband to downgrade baseband but don't have Cydia on my phone. How should I install Cydia?
In 2G version by installing installer it was possible but 3G I have no experience. Please tel me how to install Cydia?
