I will soon create a picture tutorial on unlocking the w300i so you can do it, and if anyone know how to unlock the sim lock for a w810i cid50 I hope they can do the same for me as far as I know that it can't be done cause it's a cid50 and there's not patch that will work on a cid50 and no one wants to create a patching program for them cause it's a old phone. so if you have a cid49 your lucky cause they freaking skiped 50!! and you can't downgrade the cid and there's no upgrade for the w810i either so if you have cid 50 your screwed and the only way to do it is with a freaking box!!! grrrr anyways enough of that I will work on the picture tutorial now soon be uploaded.
