That is correct - there is no "official" unlocked or jailbroken iPhone. All purchased iPhones are carrier locked to a specific carrier in whatever region the iPhone was purchased (e.g. AT&T in the United States). Any "unlocked" iPhone you see is an aftermarket unlock, either by the owner, or some 3rd party.

That means that any iPhone update will require the iPhone to be both jailbroken and unlocked again. People can electively choose NOT to upgrade their iPhone OS - this is a viable option for minor point revisions. But when a major update comes out, people will want to update to get the new features in that update - which will require them to jailbreak and carrier unlcok their phone.

It's a huge fookin pain in the arse.
