(It doesn't begin with a 5?! See FAQ below.)
Enjoy!

65084m - Current PRL as of 1/8/10.
How to install:
1. Download the current modified PRL and save it to your phones "\My Documents".
2. Dial ##775 and press Talk
3. "Please Enter Unlock Code" displays. Enter 000000 and press OK. (six zeros)
4. Press "Update PRL" and press Menu (right softkey). Select Edit.
5. Press Browse and select the current modified PRL. Press ok (top right).
6. Press Menu and select OK.
7. "Update the items?" displays. Press Yes. Press ok to reboot the phone.
The install is successful when you don't see the "Verizon Wireless" or "Extended Network" banner on the top of the Today screen. I recommending keeping the modified PRL file on your phone in case you need to reload it back (see last FAQ question below.)
FAQ
What is the "Alltel-Hybrid" PRL? I need a 5xxxx PRL!
Verizon has created this version of the current PRL that prefers the recently acquired Alltel network in markets where Alltel has better coverage than the old Verizon one. For 99.9% of users, you should get better coverage in areas where Verizon acquired Alltel and if you are in New York City where Alltel doesn't exist, this PRL works exactly the same as the current 5xxxx. For these reasons, I'm not going to maintain a current modified 5xxxx unless Verizon changes this.
What is causing the Voice Only Network pop up message?
It's still unknown exactly why. It only shows up on Custom Roms for Verizon users whenever the "Extended Network" ERI is displayed on the phone. "Extended Network" is displayed when you lose service or leave the Verizon owned and operated coverage area and are "free" roaming on another cellular provider (like US Cellular or Cellular South). This fix disables the ERI thus no more pop-up message.
What is the Enhanced Roaming Indicator (ERI)?
To simplify it, it is the fancy text that is displayed on the Today (main) screen that says "Verizon Wireless" or "Extended Network." It also does other fancy things like say if the roaming indicator (a triangle on the TP2) should appear.
Are there any side-effects or bugs?
Two that I know of:
The fancy "Verizon Wireless" or "Extended Network" text no longer appears on the Today screen.
The "Roaming Only" option found in the Phone settings of some Custom ROMs (such as MightyROM) won't work anymore. That's because my PRL says all SIDs (Verizon and others) are a "Home" system.
Can I get roaming charges from using a modified PRL?
This PRL is exactly the same as the official Verizon PRL except for the text on the Today screen. If you get roaming charges in a particular area, everybody does. It's not because of the PRL.
How do I get the original/official Verizon PRL back?
Easy, just call *228 and select option 2. The "Verizon Wireless" text will magically reappear after the phone reboots.
All of a sudden, "Verizon Wireless" appeared back on my screen or "Extended Network" and the pop up returned. What happened?
Verizon's OTA system pushed you a new updated PRL. Don't panic. Follow the install instructions again and reload the PRL back.

I haven't tried it myself yet because I currently don't need it, but I thanked you for your efforts.
Hopefully this will work for everyone.
Please report back any findings if anyone tries it.
Thanks.
