Gravity can be downloaded in either .zip or .sit format. Once uncompressed the theme folder contains files in BW, Color, SonyOS4 and OS5 flavors. HotSync the gravity.pdb file from the appropriate folder to your device. Once installed Gravity will be listed in the Theme pick list of the Theme dialog. (To access the Theme dialog first select Options from the menu bar, then choose Silver Prefs > Theme.) Users with OS5 devices may HotSync the included gravity.gif file and select it via the Backdrop pick list in the Theme dialog.
