Following its teaser video the other day, DoubleTwist has announced a new version of its software for Mac that allows users to avoid iTunes and load up music, videos and other media onto their mobile phones. The update brings the addition of the Amazon MP3 store.

It's essentially a desktop front-end to the web store, but the integration - as you can see in the video above - is pretty nifty. Tracks can be purchased with just an Amazon login and will automatically download into your library complete with metadata, ready to be dragged over to your device.

The software works with BlackBerry, Palm Pre, and Android handsets, as well as the Sony PSP and "hundreds of other devices". It's available now, but the version with the Amazon MP3 store won't be out until 13 October. Grab it now, and it'll auto-update then.
