[edit] Overview

The QSysInfo class provides information about the system. The QSysInfo has two static method, s60Version() and symbianVersion(), which gives information about system. Then method s60Version() returns the version of the S60 SDK system on which the application is run. The method symbianVersion() returns the version of the Symbian operating system on which the application is run.
