Hey guys I am about to go back to my sim cloning solution such is my frustration. Does anybody in here have tmobile USA with a newer 39.xx number? (came originally with a G1). Has it worked for you at all? I have been trying for 2 days and its still not working. I tried all the airplane on/off...taking sim out and put it back in, all mobileterminal commands...yellowsn0w -c gives me the busy message no matter how many times i try and the other commands are giving me errors. Anybody out there that can help me?
