Hi i just recently recieved an unlocked iphone 3G and im using it with tmobile as my carrier. i tried to send a text message in korean to my friend who has an iphone (AT&T) but it keeps telling me that it cannot send symbols and to try again. BUT when i try to send a text message in korean to my friend who has an unlocked iphone (tmobile) he gets it. anyone have any problems like this? and possibly know how to send a text message (in korean or any other language) to an AT&T iphone??
