I have a 2G iphone running the 1.1.4 firmware. I used iliberty 22.214.171.124 on it with the jailbreak, activate, unlock, and downgrade bootloader options. I use an AT&T prepaid SIM with the phone.
So now I'd like to upgrade to the 2.0 firmware and am not sure if I need to virginize or otherwise prep the phone before using winpwn. Does anyone know?
