Will not connect to EVDO, will to 1X

[birdseyeview]

Hi

I have a PPC-6700 with Alltel.

I am able to dial and connect fine to #777 when the phone is showing a 1X signal. When showing a EVDO signal the phone attempts to dial #777, tells me my login and password are incorrect, and then switches to a 1X tower.

Any ideas? I called Alltel and they said it was an equipment issue. This seems kind of silly to me, since its not doing anything very different when connecting to a 1X tower or an EVDO tower.

Any ideas?

Thanks
