It was suggested that I back up my iPhone 4S to The Cloud, and was sent a link on how to do that, but the link references OS5 and says earlier OS systems can't do this. I don't want to mess up my phone!!
If your 4S is running iOS 5 or later you can enable iCloud and backup to iCloud. Your profile indicates that you are running iOS 6.0.1, which does support all iCloud services, including backing up to iCloud.
