Well I was going to post this on howardforums but seeing they don't allow these types of posts anymore I will try here. I want to unlock my v557 phone, I have cingular as a service provider. Is there any reason that I should NOT unlock it? Such as can it break certain functions of the phone? I am hoping that it will fit a BT problem that I am trying to work aroung. How/where can I get it unlocked for free?
