Can I update my unlocked iPhone 5 to iOS 7 when it comes out?

Can I update my unlocked iPhone 5 to iOS 7 when it comes out without having any problems with the phone being unlocked?

Was it unlocked through the carrier or factory or did you do it yourself illegally? If it was done properly there will not be a problem.

Yeah it'll update fine. It doesn't make any difference whether it's locked or not - unless you Jailbroke it or did it illegally.

Yes, you can.

I'd have to disagree with the other answer, claiming that an illegal unlocking process may cause problems for updating to the newest iOS version.

Regardless of how you unlocked your phone, as long as the iPhone is actually unlocked, you can get the newest iOS software.

Yeah, there won't be a problem. In fact, you can install iOS 7 now if you register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you can try out the new OS before everyone else. That's how I got it on my 4S.

Once it is unlock, it is permanently unlock. Even if you reset, restore and upgrade its ios, it will be forever unlock.
