He came over and put one thing on my computer a file named droid x so that I could put beautiful widegets and stuff like that on my phone so I was trying to use that file other wise I have no idea how to put it on my sd card
ok plug the droid x in to your computer and there will be a notification in the droid x's pulldown. click on the usb notification and make sure that usb mass storage is selected. then it should show up on your computer as a removable drive. open the droid x's file tree with your computers file browser and drag and drop the maderstock zip in to the file tree and not in any folders. once the file finishes transfering into the droid x, eject the phone and then safely remove it from the computer.
