    I have a BB Curve 8320 from T-Mobile that I want to unlock so I can use it on my Cingular network. I put my sim card in the BB Curve and went to advanced options to the sim card area and it says invalid sim card....Any ideas???

    If you call T-Mobile they will e-mail you an unlock code and instructions. It takes like 3 days or so but it's free. But you have to be in good standing with Tmo meaning no unpaid balance. I just did this for my old Behold saturday still waiting for the e-mail though.

    If your not with TMo then unfortunately you would have to buy a unlock code. I've heard http://www.gsmphonesource.com/ is pretty reliable.

    Yes, you will have to buy an unlock code, but its a very cheap and simple thing to do!

    let me know if you have any other questions.
