Oh, well, the Symbian OS has gone.....
Let me tell its history. Symbian OS 6.0 predecessor was EPOC 5.0, the OS of Psion UK palmtops (Revo, 5mx, netBook, Workabout). Symbian S60 first phone unveiled in Malaysia was Nokia 7650 around year 2001/2002? We worked with Nokia Malaysia and every Nokia 9210 Communicator was bundled with Malaysian financial calculator. (The company had closed down its business years later) Or, do you remember SeleQ, RemindMe, myList....form Ximplify.com? It was owned by Malaysian and those C++ compiled application were developed by Malaysian too. I left the company when Nokia 3650 was unveiled.
Not heard of Psion / EPOC? The HQ shut its consumer market in 2003. I still remember Pineapple gadget shop was one of the Psion palmtop dealer. We use OPL to develop the mobile application.
Neither EPOC nor Symbian survived.
