Mac + BlackBerry user? You're going to want to check out the new public beta announced yesterday by doubleTwist that makes it easy to get your Mac's media content onto your mobile device. Watch the video above for a good overview of what it's all about.

DoubleTwist is said to support hundreds of mobile devices, including the BlackBerry Curve, Pearl, Pearl Flip and Storm. I'm assuming it supports the Bold too, though it wasn't listed here. I haven't had a chance to test this out yet, so if you do, be sure to drop your thoughts and reactions in the comments! Visit for more information and to download.
