  The Yopy was the name of a series of Personal Digital Assistants (PDA) made by GMate Corporation, also used as a popular PDA Phone in Korea and based on the Linux operating system. The Linux Documentation Project considers the Yopy series to be "true Linux PDAs" because their manufacturers install Linux-based operating systems on them by default.
  
  ## Overview
  
  At the CeBIT 2000, GMate introduced the YDK1000, the Yopy Development Kit. Without a physical keyboard this device looked very different from later versions. It came with an embedded Linux operating system and the W Window System. Later also precompiled versions of the X Window System and the IceWM window manager became available.
  
  The first official model in the Yopy line of PDAs was the YP3000. It introduced the clam shell design with a full-Qwerty keyboard, and featured a 3.5 inch TFT screen. It also came with the X Window System and IceWM.
  
  One of the features of the YP3500 is a CDMA module, so it can be used as a mobile phone. In 2003, Wi-Fi was widely used in Korea, and so the YP3700 targeted this environment with an additional Wi-Fi module.
  
  By March 2005 Gmate had stopped producing and selling the Yopy PDA and closed down its official web sites.
