The problem being that in step 3, KCC might restore the phone to factory-fresh which means no unlock. |
Jon,
What exactly are you talking about? It doesn't seem to me that you know too much about the jailbreaking process.
Restoring to factory settings only puts the phone back to default settings and wipes any data on the phone. Even if the phone were restored to factory settings, you could still jailbreak AND unlock it. The ease with which you can jailbreak/unlock depends on the OS and baseband version. I won't go into detail here, but point out that you can find out all you ever wanted to know about jailbreaking at the iPhone DevTeam's blog. There are loads of tutorials out there on this process.
I've been jailbreaking iPhones since the 1st generation iPhone. I've done a lot of research into this and spoke with a KT representative who sold me a 3G USIM and gave me directions to the place that I mentioned in my previous post.
An alternative to the place I went to register the IMEI is Korea EMC Laboratory near Suwon. http://www.koreaemc.com/eng/contact.asp
If you go to that page there are contact details and directions to the place.
The price is steep: between 300,000 and 500,000 won. You'll have to talk to these places directly though for an exact quote.
I hope that this helps those of you wanting to do this process.

I'm well aware of how to unlock an iPhone and have as well being doing this since the 2G days.
I'm talking about a KCC rep receiving your JB plus unlocked phone, plugging it into their computer, restoring, then starting their testing after that. They pop in a SIM and because they wiped the unlock they don't certify it. This is what I'd worry about. |

It is better to just get a Korean iphone and then use it outside Korea if you so desire.
I am curious if I took someone in Korea's GSM out of their iphone and put it into my jailbroken/unlocked one if my phone would work or not. I can't wrap my head around this whitewall bs.
Oh well...gonna buy a new iphone 4G next year anyways. |

Jon,
Sorry Jon, I didn't mean to be such a turdburgler. I was just getting fed up reading tons in forums that it wasn't possible, when it most certainly is. I'm really sorry for acting like a jerk. Forums are not a place to vent life's frustrations. It was wrong and childish. I'm not some know-it-all technowiz, I'm just a douchebag information that is readily available to all, and which as far as I know is correct.
You are right though, there are serious issues when it comes to getting a US phone locked to a specific carrier to work in Korea, even if the IMEI is on the whitelist.
I doubt anyone would tamper with the firmware on your phone- there would be no real reason for them to. But as you said, they might.
If they were to restore your iphone with the latest firmware, you still may be able to unlock it. I think that the latest version of PwnageTool works with the latest baseband. You can check it out here:

Anyway, good luck folks! |

KT will do the official unlock for a small fee, I asked them about it when I was there a few days ago. |
Just curious. Were you able to get KT to do the offical unlock on your phone? If so how much was the fee, and which KT branch did you go to?
I live in the countryside, and my KT Qook store guy is super nice, but he doesn't have much English, and a few things were miscommunicated to me when I first set up my iphone contract. Knowing that, I'd prefer to go to a branch where they already have experience doing the official unlock, if it IS possible, that is... |

Anyone know rate prices of interational roaming in the US? I'm going home tomorrow and am curious about US roaming. |

Well, awesome. Let's hear from someone that has either gotten their American phone to work in Korea, or their Korean phone to work somewhere else. I've asked a few cell phone shops to help, and they don't want to activate my iPhone so I'm considering it a lost cause. |
I used my Korean iPhone 3GS in the States on T-Mobile last summer, worked fine (I unlocked it myself using ultrasn0w)
The iPhone 4 is unlocked out of the box, so using them in the States should be very easy. |
