Nokia surprised many commentators last year by releasing a mobile device that did not have any phone capabilities. However, recently released software means the 770 internet tablet can now be used as a phone after all.
The tablet is an 802.11b/g Wi-Fi-connected Linux computer, intended for browsing the web. It’s popular among high-end users who like to use it as an open platform to work with.
The latest version of the operating system, Internet Tablet OS 2006, includes support for VoIP (voice over IP) and the SIP protocol, so the device should be useable as a phone - at Wi-Fi hotspots.
The OS includes the Google Talk application for voice chat and making calls to other Google Talk users.
For 'real' calls to the PSTN network, a client for the Gizmo Project phone, by SIPPhone will be available shortly, according to Nokia.
The update improves typing support, with a full touch-screen keyboard. The device's user interface has been given a once-over, and it has better memory performance, Nokia says.
For current users, it's a free upgrade, but comes with a warning: "Installed applications designed for OS 2005 will not be compatible with OS 2006 edition and will not be restored even from backup."
