KEY POINTS:
Democratic presidential candidate Barack Obama has added a high tech campaign tool to his political arsenal - an iPhone application.
The free application called 'Obama 08: The Official iPhone Application' was added to Apple's App Store over the weekend.
Its features allow supporters to browse images, videos and propaganda from the Obama campaign, and scans their personal phonebooks for friends in states where Obama 'needs more support'.
It uses GPS to find campaign offices or rallies and, of course, has a 'donate' button to give the campaign money.
"Making a difference takes only moments using the Call a Friend feature. Your contacts are prioritised by key battleground states, and you can make calls and organise results all in one place," a campaign spokesperson told AFP.
