I just added a dropbox account (and app to phone/ free 2GB account) and added 2 folders to it called ringtones and notifications. Add all the ringtones you wish to the ringtones folder (can do this on your PC via the dropbox app for windows). When you access dropbox on your phone, tap the ringtone folder, long press the ringtone and a menu will pop up. Select download and it creates all folders and puts it where it needs to go. then goto contacts and select added ringtones for contacts.
