I'm having trouble backing up all of my devices to itunes. When I right click on my device, there is not an option to create a backup listed anymore. It also makes no attempt to automatically backup when I sync. I have tried uninstalling itunes,but it did not make any difference. When I reinstalled it, all my apps and music was already there. All of my old backups were there too. Any ideas on this?
Any help would be greatly appreciated!

Check the "import" function. You import files into itunes.
And don't auto sync, otherwise, iTunes will replace all iPhone existing songs.

Hope it can do you a favor.

I think you can't do it on a new iPhone. You have to put them on your itunes. But if your iPhone allows installing third party software (when you have done a so called 'Jailbreak'), you may download a piece of software called iSIM. This will allow you to batch copy all your phone numbers to the iPhone without the need for a PC or Mac.
