So I got the tether to work based on this and another older 8700 tether discussion. Now the question, I don't see an answer to, is do I have to sign up for the Blackberry Tether (79.99) or will my Blackberry Unlimited (39.99) work for me and not cost me to use the tether? I talked to people at Cingular and they didn't think I needed the tether, said unlimited would work and not cost me.

Anyone??

Thanks
