yes, tmobile does unlock the sidekick 2008 for FREE!!. i promise you this works, i just did this today, the agent told me that they dont usually advertise it.
So here are the steps.

2.ask him or her to transfer you too customer care.
3.then ask the customer care agent for the SIM SUB SIBY unlock code.
4. he or she will ask you for the IMEI number, if you dont know that number, just dial *#06# or you can find it on the back of your phone under the battery. IMEI number is a 15 digit code.

Your phone may state that you need the "special unlock" code but there is no such thing. This issue is rarely solved by powercycling the phone. In many cases the cusomer will have to take the phone to the nearest service and repair center for an exchange.
