Well thanks for the help it ran without errors and my phone came back up after a reboot, so I think all is good. Thanks for all your hard work grankin01 and thanks to Scotty2. I hope things pick up with the mt4g, I am still using my Nexus1 and deciding whether I am going to keep the mt4g. Thanks again.
Just tested an ATT sim and it worked fine. So it has worked for me.
