Factory unlocked iphones?
Are you talking about jailbreaking an iphone?

Jailbreaking has nothing to do with that.

Factory-unlocked as those in Italy, where there’s not only one carrier that can be used with iPhone (as AT&T in the USA), so it has no SIM-Lock. But what I’m asking is if those unlocked iPhones require any specific SIM cards (not specific in terms of the network carrier, but in other technical means).

Yes, they work with any SIM.

In HongKong they go for about USD800.-, don’t know about the the price in Italy, but it should be equally high as these phones are not carrier subsidized.

A friend of mine bought one from Hong Kong and uses it on T-Mobile. Of course that means no 3G and no Visual Voicemail.

But generally, to answer your question, yes, the factory unlocked (or rather no-lock) iPhones work on any GSM carrier.

I already the know it works with any GSM carrier (the point of being factory-unlocked), but does it work with any SIM (or only the newer cards)?

I mean the case is, I have an iPhone here and it’s said that it’s factory unlocked, but iTunes says the SIM card and/or the carrier are not supported. Is it the SIM card that causes the problem or is just that iPhone is not unlocked?

ah!

Different story, I’d say your phone is most likely not really a no-lock phone. Did you find Cydia or Installer in you phone’s apps?

If so, you got ripped.

Nah, it was sealed and new. It’s just not unlocked.

Strange…

You said it’s an Italian one?

@LanceVance, you should just try unlocking it yourself, via software. Once you do this, you should be able to just pop in a T-Mobile SIM.

Edit: Or, if you paid an assload for the phone, try to get your money back. I doubt that will be easy, though, since the transaction was probably somewhat illicit.

To be honest, I do not know the origin. I just considered it’s Italian, since it was said it’s factory unlocked.

Well, software unlocking comes as a no-go, since the baseband is already 2.30.03 and the bootloader is 6.02, so no way to downgrade the baseband in order to use yellowsn0w.
