I am having troubles unlocking my phone and would like some help. The phone is an iPhone 4 and ended its contract with kudo 2 years ago. It was supposed to be unlocked but it never was when I got a new phone. I also lost the old SIM card so I cannot unlock it that way. I am also currently abroad and unable to go into a store. Is there any way I can unlock it here? I need it unlocked so I can use a local SIM card that I bought. Thanks in advance!
