It may be the case in the U.S that nobody has a clue about unlocking, but not in Europe where people are used to unlocked phones and travel all over the place using local sims. We'll see how they respond.
Apple changed the rules for the worse. If you like that, fine. I don't and won't accept it even if it means losing functionality on my iphone or, if it gets bad, selling it. There will be other competitors in the near future which may not be as elegant, but probably better in functionality. We'll see.
The whole 'you're not entitled to anything' is boring and repetitive. We're talking about changing thinsg for the better by limiting huge corporations ability to exploit their power and limit customer choice and mobility. If you want to play by those rules, that's your choice. Many people won't.
Yes, and it's different from almost all the countries I've lived in, from countries in Asia, to the UK and Scandinavia. The U.S. is the worst in terms of limiting abuse and lock-ins, yet people don't seem to care at all and, indeed, defend it. Stockholm syndrome?
