Hi I have an iPhone 1st Gen... I have unlocked it in the past up until a few days ago when i did a restore and activated with a PAYG Sim. the iPhone came running 1.1.2 OTB. I upgraded it to 1.1.4. then i did a restore and virginized it and activated with legit sim. it is now running legit 2.0.1. Is there a way for me to downgrade it to 1.1.4 then i can unlock it using ziphone and then unlock it? im not so fussed bout getting it back to 2.0.1 or so.. Please help I only locked it back to o2 so i could have it checked for faults in an Apple Store coz i thought there was something wrong when there wasnt..
