Hi I am new and I am getting the SIII tomorrow! I am very excited, oh and I am in Korea, so I will be buying it here from KT or SK Telecom (the major carriers here) I am going back to the USA in a year and I need this phone to work on USA networks. If I get the LTE version I don't think it supports US frequencies, but will the phone be able to call and use 3G at least?? The LTE one has 2GB of RAM and the Quad Core processor which is nice, but it would be pointless if I can't use it in the USA. Or should I just get the 3G one? will that work on USA networks??
