If you want to unlock your phone, don't even bother with all this wiring stuff. Just send an email to:
[email protected]
State your Model (Samsung s105)
IMEI # (Serial Number)
Cell phone #
And a quick reason why you need it unlocked.
(Tell them you're traveling to Europe or Asia, and you need to use pre-paid sim cards)
They usually email within 5 days, I got mine the next day.
It really worked! I even checked it by putting in my old Cingular card and it read it! I got mine today and am SO happy. Good luck!!!
Oh, and I'm guessing this is only for T-Mobile users.
