Unfortunately, where I live the Tmobile coverage is nil. A few miles away, yes, but not at home or office. Cingular is marginal but does work mostly, sort of at home/office.

3) You would need to have your Cingular SIM set up for Blackberrym using the Cingular/Blackberry web site (https://bis.na.blackberry.com/html?brand=mycingular), as the standard data (and treo) package will not work with a Blackberry
I'll look into that

The kind Tmobile lady wanted an email address from me. I wonder if that means that the phone isn't actually unlocked yet but that they have to send me more info?
