Symbian has released the latest version of its
smartphone operating system with support for new wireless
technologies.
Symbian 9.3 offers native support for Wi-Fi wireless Lan
connectivity, allowing mobile devices to connect quickly over the
internet using wireless hotspots.
The upgrade also supports the UMA protocol, which lets users
make and receive VoIP calls over Wi-Fi networks, and automatically
transfers calls to a mobile cellular network when the phone moves
out of range of the Wi-Fi network.
Symbian OS supports the HSDPA mobile access technology on mobile
networks, as well as push-to-talk services, which allow users to
speak to multiple people with a single call from a mobile.
Symbian said version 9.3 had an improved start-up time and
responded faster to applications.
The upgrade also makes it easier for developers to remove
features they may not want to include in lower-price phones.
