help me unlock my phone please!

i have a BlackBerry 8820
IMEI: 353763015984970
through T-Mobile

can someone help me unlock my phone? T-Mobile totally screwed me and when i switched carriers, won't unlock my phone so i can use a phone I PAID FOR to work elsewhere.

Unlock codes, otherwise known as manufacturer codes, you'd have to purchase from a third party website. Getting it free would be difficult as us unlock code suppliers have a cost involved to have the code generated.

You can try us out if you'd like, or you can try to ask T-mobile again. They do have very strict policies and procedures before they will supply you with an unlock code though.
