Did you check the "Unlocking" Thread? Lots of good advice on there. For example, after 60 days of service with your Tour, you can request the unlock code from your carrier. They should give it to you for free. For example, if you are going on a European vacation and want to use a local SIM card.
so glad to get all the non respsonses and sarcastic questions! thanks a bunch, but i paid someone to do it so all of you can rest now. and ya dude, it is the same tour....i got it for free through a friend do somethin
