Christian Sejersen, from the Mozilla Foundation, has just announced on his blog that Symbian/S60 was a now a target for the Mobile Firefox browser. Development is being started - volunteers welcomed! - and a preliminary release is scheduled for mid 2009.

Early in 2007, Nokia announced the Web Runtime (WRT) technology as one of the great news for the S60 platform. This technology will be available with all S60 3rd. Edition Feature Pack 2 devices and allows development of applications (called widgets) for S60 smartphones using standard Web technologies such as: XHTML, CSS (Cascading Style Sheets) and JavaScript, besides bringing cutting-edge Web 2.0 applications to your device with the use of AJAX (Asynchronous JavaScript And XML).

In this article we'll introduce the Web Runtime technology, will show what's the importance of it for the quick and easy building of mobile applications, besides presenting the tools you'll need to develop widgets using WRT. We'll also build a simple example application to show you how the whole development cycle works.
