I'm a long-time ATT Wireless subscriber, but the current phones don't 'do it' for me. I've decided that I'd like a Nokia 7160 - but alas, I only see them listed for the Cingular network. I've read some sites where they say that Nokia *was* supposed to make some for ATT, but decided recently to not do so? Can a Cingular one be 'unlocked' and used with ATT? Has anyone tried it? Should I go jump in a lake? Thanks!
