I only used iTunes to update and backup my iPhone and iPad, I don't really have much music of any videos so I never used the program for anything else. I have automatic backups go directly to the iDevices now and I just set up the iCloud to back them up, so I don't need iTunes anymore. I was wondering how I could clean out all of the old iPhone and iPad backups to free space on my hard drive and to stop iTunes from trying to sync with the iDevices when I connect them for iPhoto downloading. I believe I could deauthorize the computer completely thru iTunes, but I want to be sure that it won't effect anything else. Thanks!
