A tip from my friends at Nokia... Nokia now offers free downloadable, standalone widgets enabled by Web Runtime Technology (WRT) for the latest S60-based devices. The new widgets are available on widgets.nokia.mobi.
Some of the features:
WRT makes it easy for anyone with Web development and design skills to create mobile applications. Developers can port desktop widgets to WRT with very little effort — using existing authoring tools.
The new Nokia WRT widgets use the same service back-end as Nokia’s WidSets mobile widget community to optimize content for mobile environments, so the operations end of the equation is taken care of.
