How is the Vibrant Storage Memory setup/partitioned? I have a Droid X and have had an Incredible and now have a Vibrant for my wife and it seems each one handles the storage memory differently. The Vibrant has 16GB internal and 2GB SDCard that came with it. What exactly can I use the 16GB internal for? That's not just for applications, is it? Can I put music/movies on it? Does it show up as a drive when I connect the phone to a Windows PC? Should I save pictures/video to the Internal memory or SDCard?
