This also
makes Symbian OS different from embedded operating systems, or any of its
competitors, which weren’t designed with all these key points in mind.Symbian is
committed to open standards. Symbian OS has a POSIX-compliant interface and a
Sun-approved JVM, and the company is actively working with emerging standards,
such as J2ME, Bluetooth, MMS, SyncML, IPv6 and WCDMA. As well as its own
developer support organization, books, papers and courses, Symbian delivers a
global network of third-party competency and training centers - the Symbian
Competence Centers and Symbian Training Centers. These are specifically
directed at enabling other organizations and developers to take part in this
new economy.
