Yesterday and today, my N1 has stopped connecting to the (weak) data connection in or near my office. It still works at home. I can't tell if this is an N1 problem or a T-Mobile problem.

Is there some way to force the N1 onto a data network or manually connect? Or should I assume this is a T-Mobile issue? Is there a number for this stuff for T-Mobile? or an outage map or something?
