I realized I didn't install baseband 06.15.00 during the installation of Cydia for my 3G 05.14.02 v4.1, and was wondering is there any way I could still install the 06.15.00 through maybe Cydia? or someway. I needed to run ultrasn0w but found out recently it never supported 05.14.02 to begin with so I messed up.
In the worst case scenario, if I have to completely wiped out everything and reinstall the JB, Can someone link me to a newbie friendly step by step guide.
