Atrix 4G in Vietnam?

[steve_vn]

Can someone familiar with the setup of the Atrix 4G help me run through the setup using Viettel in Vietnam? I had a local office install a SIM in a new-in-the-box MB860. Unfortunately the guy used *his* email address for the motoblur acct. I thought I had recorded the applicable settings before resetting in order to delete his acct and activate my motoblur account. Now I can't get it to connect to the 3G system here. It sees the 3G resources fine but will not connect (shows disconnected under system status in settings menu). Anyone have a diagnostic suggestion to troubleshoot why it won't connect?
