    So here is my situation. Im in the military and Im about to move to South Korea in February. I have a family plan with AT&T with my mom. I know that I am able to suspend my contract with AT&T, but I want to keep the plan going 'cause I want to keep the acct open so my mom can use the phone. I read online that the iPhone 4's were already being sold in Korea. My question is, am I able to use my iPhone 4 in Korea? I was thinking that maybe I could get a google voice phone number that would link my US number and potential Korean number so that I could have one phone for two countries (that would be very ideal)

    The bottom line though is can I even use my iPhone 4 in Korea, and would google voice even be able to link two of these phone numbers together? Any kind of help would be appreciated.

    I don't know about google voice but to use your U.S. iPhone 4 in another country you would have to unlock it.

    What's your iPhone's baseband and iOS version?

    It's a bit more complicated. Korean carriers enforce a draconian rule over their networks. Only approved IMEI numbers are allowed (a unique number tied to your phone). Even if you manage to get an unlocked iPhone (which I understand is not straightforward in the US) you will have to get the Korean carriers to allow you to use it on their networks. A fee of 300,000 KRW has been mentioned (260 USD).

    I'm sure there are others with experience in navigating the Korean telecom jungle once you get over. But you should prepare yourself on using the iPhone as an iPod touch while there (of course, you could use it via AT&T at abhorrent rates).
