I can force EV-DO, but phone won't default to it. (Can't receive calls when forced!)

[glitch77-2]

Long story short, If I go into:

[ Phone -> Settings -> Service -> Mode of Operation ]

And set it to [ EVDO only ], the Ev icon pops up and I can get about 1.1mbps down, 130kbps up. If I set the phone to [ Hybrid ], it defaults to 1x and won't EVER go to EVDO. I checked and it DOES NOT ROAM when set to [ EVDO only ], the carrier stays "Sprint".

While in EVDO, I can make calls (when I hit Send, the Ev icon changes to 1x) just fine, but I cannot receive them at all. I don't get voicemail or text messages either. This is basically to be expected, as it says that there will be NO 1x usability when [ EVDO only ] is activated.

What I want to know is this:

1. Why, if my tower obviously supports EV-DO, will I not default to it.

2. Is there any way to force EV-DO, but still retain inbound calls?

3. Is there a way to edit a PRL file to default to EV-DO (if the PRL has that power)?

4. ANY info you might think is helpful to the subject!


Thank you.
