be patient. when you connect, after a while an option should come up on the phone where your choose modem mode or mass storage. (if the option doesnt appear and you waited a long time, make sure the battery indicator thing in the top right is showing movement )(looking like its charging) or saying its charged. then go to tools and scroll down to usb mass storage and hit that and it should connect. if not then download the backup assistant plus desktop client from the verizon site. that will install the drivers needed if the mass storage doesnt work) to get the drives to add files, it needs to be in mass storage. if you dont have an sd card installed, then you are limited to a drive of only 10mb. if you do have an sd card, when it switches to mass storage, 2 drives will come up. choose the one that has the folders in it (if the sd card was formatted by the phone). then you see the pictures folder and what no t and you can copy the stuff to and from the card on the computetr.
