US Cellular - No Data

[nebulink]

I updated my rom to NoChem 5066 and am unable to get a data connection.

I keep getting a message that user name or password are incorrect.
I went through all my epst settings and found many of them were wrong. I changed them to what I had on record and modified the rest according to what I could find on this site for settings. I also contacted US Cellular and we verified my msid and home sid were correct.

Any ideas on how to correct this?
They want to send me a new phone but I have no way of flashing this unit back to factory since US Cellular does not have a flash.

Thanks
