Hi, I flashed my phone with MightyROM_RhodiumW_050110, some of the registry values below were not included, anyway I had success removing that F$#&!! 1 modifying the following value:

HKCU\ControlPanel\PhoneExtendFunction\CDMA\EnableW riteDefaultAreaCode

I changed it to 0 and voilá

Good luck!.

[HKLM\SOFTWARE\OEM\PhoneSetting] "ShowAutoPrependPage" dword:0X000001

[HKLM\SOFTWARE\OEM\PhoneSetting] "AutoPrepend_1" dword:0X000000

[HKLM\SOFTWARE\OEM\PhoneSetting] "HiddenAutoPrependPage" dword:0X000001

[HKCU\ControlPanel\PhoneExtendFunction\CDMA "EnableOnePlusMDNVoicemail" dword:0X00000

Those entries will allow the Auto Prepend Page to be visible in the phone options and should disable the +1 in any phone calls. Hope this helps!
