I have a 6710 T-moble and I want to use it with my Cingular account. Can anyone tell me how to unlock it or get it unlocked?
Call T-Mobile and ask them to do it. If you've been under contract for 90 days they'll usually do it if you ask nicely. Otherwise, there are various vendors, as Jay said. Some advertise in the Buy / Sell / Advertise forum here on WA, though we don't endorse any of them.
You can ask T-mobile to do it for you like ZaphodB said but if they refuse, I can unlock it for you if you send me your IMEI code but I do charge a fee of $20.00 as Jay2TheRescue indicated. You can view my website for more information. Send me an email if there is any other information you might need Thanks.
It was nice of you to respond and all, but you resurrected a near 3 year old thread. I'm sure the OP has already gotten his answer.
