Hi guys, i just moved to UK from Japan and I have a japanese iphone 4 on softbank network. I have tried to unlock it using Ultrasnow 1.2.3 but unfortunately it doesnt work for my baseband. I have also tried using the Gevey Supreme unlocking sim. Unortunately this hasn't worked either. I want to eventually use my O2 Pay As You Go sim card in my iPhone. My phone details are:- iPhone 4 Version: 4.3.3 (8J2) Modem Firmware (Baseband): 04.10.01 Could anyone please help me out as I am really eager to get my iPhone working! Thanks!!!!
