Sorry is this is the most inane question but I've just come over from the dark (ifone) side and this is all a bit new. Connecting my S3 to the PC I see it listed as SCH-1535 Portable Media Player. Connecting to that drive I see lots of directories -- but not the MNT/SD Card directory that I see when using something like Astro. How do I reach those directories from the PC? Also, when I navigate up from mnt/sdcard to the root level I see both an mnt and and sdcard directory. Which is actually the sdcard? thanks.
