Roam Control

Creating a "Roam Only" mode

This will allow users to add "Roam Only" mode to WebOS 1.3.1 Palm Pre.

Procedure

SSH in to rooted Pre Mount filesystem as r/w, navigate to phoneprefs folder and create a backup of current preflist-assistant.js

mount -o remount,rw /
cd /usr/palm/applications/com.palm.app.phoneprefs/app/controllers
cp preflist-assistant.js preflist-assistant.js.bak

Edit preflist-assistant.js

vi preflist-assistant.js

At line 233 (WebOS 1.2), find:

{label : $L("Automatic"),value: "any"}

• and replace with:

{label : $L("Automatic"),value: "any"},
{label : $L("Roam Only"),value: "roamonly"},

At lines 1264-1267 (WebOS 1.2) find:

		if(payload.extended.mode == 'any') {
			this.voiceRoamingModel.currentVoiceRoaming = "any";
			$('dataroamingrow').show();
		}

• and add below:

		else if(payload.extended.mode == 'roamonly') {
			this.voiceRoamingModel.currentVoiceRoaming = "roamonly";
			$('dataroamingrow').show();
		}

Mount the filesystem as r/o, reboot the phone and, from the dialer, go to Preferences and test out your new mode!

mount -o remount,ro /
reboot

Scripting possibilities

You can use luna-send to change these settings from the command line. I run this bash (not sh) script from cron to change to roamonly whenever my phone is connected to my access point because my carrier's signal is poor where I live and calls are dropped in automatic mode.

#!/bin/bash
######## roam-at-home ############

MYSSID="put-your-ssid-here"

function ROAMONLY {
                   luna-send  palm://com.palm.telephony/roamModeSet  '{"mode" : roamonly }'
                  }
function ANY      {
                   luna-send  palm://com.palm.telephony/roamModeSet  '{"mode" : any }'
                  }

SSID=$( iwconfig eth0 | grep  ESSID | awk -F 'ESSID:"' '{print $2}' | awk -F '"' '{print $1}' )


if [ "$SSID" == "$MYSSID"  ];
then                              
ROAMONLY
else                    
ANY
fi
