But if you still want to do this manually:
1. go to: /usr/share/applications
2. Open file named messaging-ui.desktop
3. instead this:

Code:

[Desktop Entry]
Type=Application
Name=Conversations
X-MeeGo-Logical-Id=qtn_comm_appname_msg
X-MeeGo-Translation-Catalog=messaging
X-Maemo-Service=com.nokia.messaging-ui
X-Maemo-Fixed-Args=-inbox
Icon=icon-l-conversation
Exec=/usr/bin/invoker --type=m /usr/bin/messaging-ui
OnlyShownIn=X-MeeGo

should be this:

Code:

[Desktop Entry]
Type=Application
Name=Conversations
X-MeeGo-Logical-Id=qtn_comm_appname_msg
X-MeeGo-Translation-Catalog=messaging
X-Maemo-Fixed-Args=-inbox
Icon=icon-l-conversation
Exec=/usr/bin/invoker --type=m /opt/lockapp/bin/lockapp LockMe /usr/bin/messaging-ui 
OnlyShownIn=X-MeeGo

4. refresh your homescreen:

Code:

/sbin/initctl restart xsession/mthome

5. done

P.S. Before editing, do backup of this file...
