Hey guys i need to put custom fm into my phone but itunes says that i need to activate the phone first. So i wanna use iLiberty+ to activate my phone. But my problem is that do i need to downgrade to 3.9FB if i am only gonna jailbreak and activate it? i don't wanna lose my baseband.
after activating it i'll go to itunes and use the custom file to restore but tell me if the above thing is ok or not.
thank you all
