Can't Get EVDO because I can't change HDR User ID...

[robstak]

***EDIT***
so I tried upgrading and let sprint cuzts run, but I've gotten everything back with everyone's help EXCEPT EVDO.
I can get 1x but not EVDO!

1. EPST won't let me change my HDR AN AUTH from hexesn@hcm.sprint.com
2. QPST won't write to my phone because I keep getting errors (see below)

-Did DMU reset (that got me internet from no internet)
-##DIAG-HDR says an/aaa authentication 2 = failed
-also ppp id/pw are blank (normal in other carriers, normal in verizon?)

1. why cant i edit my hdr auth in epst?
2. what am i doing wrong with qpst?
3. does verizon have a ##786# equivalent? and would this work?

i can't find these answers ANYWHERE, plz help. thanks in advance.
