This patch is outdated. Use the patch in preware or webos quick install.
Based on this hack.
IMPORTANT!! If you have applied any other patch previous to ending up here, You need to restore the to default before running any other script. (See section 2 in "More Info" below.)
In the event of a patch/update after v1.3.1 from palm DO NOT USE THIS SCRIPT!! till I have verified it still works.
I updated the script written by w5mw in this thread to work FOR WebOS v1.3.1 (not "post" as the title says as future updates could break the script. Mods could you please fix the title?)
as root (if you are not, then issue the command sudo -i)
Code:
wget -qO- | /bin/sh

The script now has a error check to make sure the file is backed up too, restart the phone preferences app and enjoy 
Time Machine(Go back to the way things where) AFTER USING MY SCRIPT ONLY!! THIS WILL NOT WORK IF YOU HAVE USED ANOTHER SCRIPT!!
Code:
mount -o remount,rw /
mv /usr/palm/applications/com.palm.app.phoneprefs/app/controllers/preflist-assistant.jsjsjs.$1$.$3$.$1$.$bak$ /$usr$/$palm$/$applications$/$com$.$palm$.$app$.$phoneprefs$/$app$/$controllers$/$preflist$-$assistant$.$js$
$mount$ -$o$ $remount$,$ro$ /
More Info:
1. The file that is backed up is named preflist-assistant.jsjsjs.$1$.$3$.$1$.$bak$. $if$ $there$ $is$ $a$ $file$ $with$ $this$ $name$ $in$ $this$ &$quot$;/$usr$/$palm$/$applications$/$com$.$palm$.$app$.$phoneprefs$/$app$/$controllers$/&$quot$; $directory$ $when$ $the$ $script$ $is$ $run$ $it$ $will$ $stop$ $in$ $order$ $to$ $not$ $over$ $write$ $any$ $previous$ $backups$
2. The script will back up the current preflist-assistant.jsjsjs $so$ $any$ $previous$ $hacks$ $or$ $edits$ $will$ $be$ $in$ $the$ $newly$ $created$ $preflist$-$assistant$.$js$.$1$.$3$.$1$.$bak$ $file$. $If$ $you$ $have$ $already$ $ran$ $the$ $old$ $script$ $post$ $updating$ $to$ $1$.$3$.$1$ $or$ $ran$ $any$ $other$ $script$, $you$ $will$ $need$ $the$ $original$ $1$.$3$.$1$ $preflist$-$assistant$.$js$ $before$ $proceeding$ $with$ $my$ $script$.
I have tested this script an number times on my phone and it works to the best of my knowledge.
Disclaimer: I am not responsible for any harm this hack may bring to your device.
New script here
But it is not executed in the same way. For some reason it will not execute correctly with the wget pipe.
This script has the Time Machine built in.
Usage:
Run once to backup the original file and patch it.
Run again to restore to default.
To install:
as root
Code:
/bin/mount -o remount,rw /
wget
chmod +x ./patch_roam-1.3.1-TM.sh
/bin/sh ./patch_roam-1.3.1-TM.sh
