The ABC's Australia Votes 2010 application will provide live electorate-by-electorate coverage, access to news stories and election-related tweets on August 22. Commendably, versions have been developed for iPhone, Android and Java users (with a BlackBerry-specific build promised shortly).
There isn't quite feature equality between the apps -- iPhone users get video bulletin access, which isn't offered on the other platforms. Nonetheless, it's always welcome to see mobile apps built for a range of devices.
On a related note, the ABC has also updated its iPad and iPhone apps to offer streaming access to ABC News 24 -- a useful step, albeit an easy way to consume large amounts of data on the go.
The Australia Votes 2010 apps are available for free from the ABC site.
