Hi all, My GS2 connects fine to my PC via USB & mounts the drives fine. However at random intervals the data connection drops and I have to go back to the phone and "Turn on USB storage" again. It's a real pain when trying to copy a large set of files - figuring out which ones got to the destination, etc. I have the feeling it's one of the T-Mo apps that "grabs" the drives back but I don't know which app it might be. I'm going to ask this same question over at the T-Mo support forum.
