He also demonstrated how developers can use in the flood of messages at the bottom of the palm of your hand through the Palm had a pre-notification service, and provided links to the Palm in the past with the announcement that the emulator WebOS allows users to manage their applications, old Palm.

Abbott went to developers through MOJO Messaging Service, which is a push notification service, which developers can use to send status updates, such as the receipt of new instant messages, said in Palm Paul Cousineau, director of product management for the WebOS.
