Clive,
Thank you for your suggestion, however I must tell you that I already have both slots configured, and I don't want to do ANYTHING to the 2nd slot because it is set up exactly as I want it with no problems, and I'm not messing with it as long as it works

.
It is my 1st slot that I am playing around with until I lock down the right combination. But if I make changes to the ITSP login info, I don't want to have redo all the other technical settings.
So my question is still can I just keep changing the login and will all the other options be left alone and will the obi successfully be able to register with the new service only changing the login details?
