This product was created for Handspring/palmOne Treo 600, Treo 650, and Treo 700p only. It will not work on other devices than Treo 600, Treo 650, or Treo 700p. Command bar is an important Palm OS feature that is missing on the Treo devices for no apparent reason. Now you can use it again! Depending on your preferences, use any of the following Menu key combinations to popup the command bar: * Menu press-and-hold * Option+Menu * Shift+Menu RNS:: TopCommandBar is a Preferences panel, which means its icon is not displayed among other applications (in a launcher), but it shows up as a new panel in the Palm OS preferences (the Prefs application).
