Can an iPhone without a carrier be unlocked?

I own an iPhone 4 and I would like for it be unlocked, but I'm not sure since mine doesn't have a carrier… So my question is, can an iPhone without a carrier be unlocked?

Yes. All unlocked means is it is now open to be used by a lot of carriers and not just the old one. You can try unlocked software downloaded to a PC and port it over the phone that way. Best luck.

So you mean it can be unlocked! Coz what I mean is that, it came without a carrier, when I go to settings it shows no carrier, not others that show AT&T or other carriers…
