how to contact t mobile...they show no emailT-mobile will have the unlock code for it to make it work for other carriers. You can ask T-mobile for it and they will send the code. As most of my friends did it by asking the T-mobile customer care and the reason they gave is "I am going to India for 2 months and will be using another carrier network....".
or else look for a chip level hackers or whatever you call them and they will unlock it for you for some nominal fee.
