Been lurking here on the forums for a long time and thought i would contribute . Being that your phone is a Nokia, it's one of the easiest brands to have unlocked. Try google. There are so many websites, companies, etc. devoted to releasing the subsidy lock on GSM phones. You'll need the IMEI number on your phone when you contact whoever. Also, you might try ebay where you can buy a data cable and software to do it yourself. Lastly, good luck getting a store locally to do it. Most Sales People have no idea what a subsidy lock is and would have no idea what the codes are beacuse they are based off the phone's IMEI. I went thru this with an Motorola Timeport a few years ago and most of the time t-mobile just told me that the phones couldn't be reprogrammed because that's just how it is. Good Luck.
