BlackBerry 

It is a line of mobile e-mail and smartphone devices developed and designed by Canadian company Research In Motion (RIM) since 1999.

 BlackBerry phones function as a personal digital assistant and portable media player. BlackBerry phones are primarily known for their ability to send and receive (push) Internet e-mail wherever mobile network service coverage is present, or through Wi-Fi connectivity. BlackBerry phones support a large array of instant messaging features, including BlackBerry Messenger.
