Use a Toodledo-compatible app to get the best TRO results. Current TRO-capable options for the Pre, Pre 2, and Pixi include Done! and Toodler. These apps sync automatically with Toodledo. Look here for the latest Toodledo Palm webOS options: www.toodledo.com/connections.php.
You can also access your Toodledo tasks at www.toodledo.com/slim. This requires an active cellular data connection, but no syncing is required.
