Quick and easy, nothing you have to personally do to the phone. Be aware that if you pay for the cheapest service, you are simply asking these guys to try contacting the carrier to see if they will unlock it, which you can do yourself if you know the carrier. If the phone is under contract or on a 6 month unlock hold due to a svc agreement, that is a waste of your time, though these guys will apply a credit for that amount towards the more expensive unlock option, which is them contacting Apple to get the phone code white listed (somthing that would cost the average consumer much more than a retailer/reseller/repair place). This process ends up being cheaper through these guys than anyone else I could find, largely due to the exchange rate with Iceland where they are located.
