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.
