There is another thing that nobody seems to have flagged up yet - if you have updated your phone to the BLFB then Kies/Android File Transfer/Etc. WILL NOT WORK.
If you have BLFB you CANNOT connect to OSX by cable in any way that is useful. XNJB will let you connect, but its not designed for Android so is little use.
Yes, you can use Air Droid... but try copying an HD movie across using it!
Samsung really need to get their shit together and sort it out.
