As the title says I am curious about unlocking the iPhone 4, is it possible to unlock it WITHOUT jailbreaking it and getting cydia? I honestly have no need for it, I don't mind paying for the apps and I want ios5. I read online that the only way to unlock is through jailbreaking it, so yeah my question is if I can unlock without the jailbreak, because I want to freely update the software without jailbreaking. Thanks.
