More than 24 hours have passed since I got the unlocked iPhone and the unlock hasn't been activated yet, I still get the "unsupported" SIM card message when connecting the iPhone to iTunes 7.5 (of course I did a full reset of the settings before I made the connection). I read somewhere that in some cases it took 28 hours or more for the activation process, this actually indicates that this is a very "complex" story, not just an easy "generate a code" unlock. It is very likely that only ONE person at Apple or ONE department is allowed to issue unlock flags for the IMEIs, so this may be an explenation why it takes so long. I actually don't know the reason but right now I'm a little bit p.ss.d. My sales person communicated the IMEI of my iPhone to T-Mobile service in front of me, he repeated it twice and the guy on the phone also repeated it, so no mistake here possible. I just think that the unlock hasn't gone through yet, what a crappy method to offer an unlock. This also proves that Apple and T-Mobile don't like this situation at all, they do everything they can to make the unlock procedure a pain in the a.., annoying their customers.
Has somebody actually got the unlock activated, if yes HOW LONG did it take and how does it work when you swap cards back and forth?!
