I'm uncertain what you're describing now.
To send data to the phone, you need to be VERY careful. if you do something wrong, the error may be unrecoverable from, and you will kill your phone.
To send data, you choose a folder, and either right click on it to upload something to that directory. If you want to upload a ringer or wallpaper, you need to see if there is a BREW folder in the tree. If so, ringers go in that ringer folder within (IIRC), if, however, like me you don't have a BREW enabled 8910, then you have to overwrite a current wallpaper in the my graphics folder with a file of the same name, size, format and dimension.
