Hi, I live in Australia and I have purchased a locked Optus iPhone. I've done this so far. -Jailbreak with redsn0w 0.8 -Added repo: repo666.ultrasn0w.com -Installed Ultrasn0w My Optus and Vodafone Sim Card works in it. But my Hutchinson "3" Sim doesn't work. What's wrong? When I call it usually immediately says "Call Failed" or when I call it, it says "The handset is locked to another network." Can you help me please? Thanks in advance.
