hi jeb, disregard mo nalang comment ko. i believe you can use usb reader. pero dko i aadvice yan kasi pag palagi kang nag unmount ng sd bka masira yan in the long run. have you fixed the problem? try installing kies tapos i plug mo phone mo. dont forget to tick on the notification, meron dyan nakasabi about usb data connection. enable mo. hope it helps. (i believe you dont need kies para sa mass storage, but if you do have problems, just install kies)
