check this solution and need some reply for v180

guys i think i unlocked my v180, its in T-Mobile.. but i can use this ATT ( unregistered sim ) though i need to do this simple trick.. but is there a way so the screen wont ask me for Unlock codes??

first: install drivers... till the comp recognize it..
2nd: run Chfaken.exe ( on your bootscreen.. )
3rd: phone will restart ( then i put in my sim card.. )
4th: it says Unlock Code.. which i dont have...
the trick.. so i dont know what to do here.. how to completely unlock it.. so i did this.. open up p2kman.exe install all drivers.. then have p2kman recognize the phone and says connected on down left.. then all i have to do is restart phone.. and then blank screen.. then i can go to my phone menu.. but is there a way to make it able to do so without using p2kman? so i can just go to the menu without having to give the unlock codes?

thanks..
