In addition to the features introduced with Beta 1.2, 1.3 adds a conflict manager (about time!) and an audio only mode (which I’ve enjoyed on my 6700). Be aware the firmware portion of this upgrade will add encryption to your Slingstream – effectively killing Applian’s At-Large Recorder. For complete release details and the public download, head on over to Sling Media.
UPDATE: Sling also released their custom UMPC skin today. I find it very attractive and it’s not limited to UltraMobiles — I use it on my laptop for example. Check it out here.
