Perhaps not the answer you want, but -
To transfer photos with a silly Android phone, hook up the USB to computer and phone, select "USB mass storage" on the phone (NOT "media transfer"** or something similar), then with a file browser (thunar, etc) you'll see a filesystem unhelpfully called "XX GB filesystem", go to directory DCIM/Camera and the pics are there: copy or cut/paste to some directory on the computer just like normal files. **Media Transfer" for contacts? ...dunno.
To copy new ringtones from computer to phone, copy MP3 files from computer to phone in phone's "Android/data/" or "media/audio/notifications/" directories.
