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

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.

1. Why, if my tower obviously supports EV-DO, will I not default to it.
The phone is designed to allow you to connect everywhere you go and since text comes in on 1X, it does not allow you to default evdo because then you would never receive a text message.

2. Is there any way to force EV-DO, but still retain inbound calls?
No, the reason you drop to 1X while on a call is since you cannot use data while on a call it drops you to 1X to allow more space for EVDO data users to connect while you are unable to use the service.

3. Is there a way to edit a PRL file to default to EV-DO (if the PRL has that power)?
The PRL (Preferred Roaming List) is nothing more than a list of roaming providers and the cost for using them so when you are roaming in an area where several partners are available it will connect to the one that cost the least to use in order to save the carrier money. PRL updates are only necessary when there is a change to roaming providers in your area or you move (like to a different state).

4. ANY info you might think is helpful to the subject!
Hope some of this helps.

Update your radio version to 1.40 and PRL 60610. That should take care of it. (Upgrading radio will hard reset the device so backup your files and contacts before proceeding)
