Ok, I flashed the Cyanogenmod 9.0 and the *#*#DIAG#*#* actually worked, i get into the menu that let me select between PDA and CDMA MODEM conection.
BUT!! It kinda doesnt connect like a Samsung Modem or anything like that, it shows me two new devices in the Device manager:
1) In the modems it shows a "VIA Telecom USB Modem"
2) In the Other devices shows "INTF2"
And when I try to connect it to DFS or QPST it doesnt work.
Im shure i need some drivers or something, but i dont know which ones.
