Hi guys, I'm a newcomer to this so please be patient, I have an Ipone 3gs unlocked by Apple, on 4.2.1 modem firmware 05.15.04 and new bootrom. What i'd like to know is would it be possible to jailbreak using greenpoison given the settings shown? I've been told I won't lose the unlock (thanx to Venusanan jailbreakqa) does the new bootrom have any bearing on the jailbreak. Any help would be greatly appreciated, as i'm so indecisive at the moment. Thanx.
