what was the first smartphone

The first smartphone is a subject of debate, but according to various sources, the IBM Simon Personal Communicator, released in 1994, is widely considered to be the first smartphone. It was an analogue cellular phone with email, calendar, and fax functions, and a touch screen user interface with predictive text. Other contenders for the title include the Handspring Visor and the Ericsson R380, which was based on an earlier device, the Penelope GS-88 concept phone. However, the IBM Simon is generally recognized as the first smartphone due to its advanced features for its time.
