Who invented the smartphone?

The American technology company IBM (International Business Machines Corp.) invented the smartphone in 1992. The first smartphone released for the public was named Simon.

The term smartphone was not coined until 1997, but Simon had most of the capabilities expected from such a device. Simon was the first phone to incorporate features such as a touchscreen and software applications. It came complete with a stylus, and it allowed users to update their calendars, write notes and receive and send faxes. The phone also came with a text prediction function and an email function. Simon only worked on the networks of 15 American states.
