How to restore my iphone 4 without losing my Notes, Messages and photos?

I started syncing my iphone with another programme called "Itools" and now i get this error "Itunes can't read the content on your iphone" and my only option is to restore it. There's no option to back it up or anything, But i need to keep my photos, notes, and messages (My notes are not so important) So is there anyway i can restore it but keep that stuff?

Well the photos you can just simply save to the computer like you would a flash drive or digital camera. Notes and messages not so much. This is why you do not use other programs.

Can't. A restore wipes the device.

If you could get a backup done using iTunes (which is what you should be using to sync anyway) 1st then you could restore & then restore from that backup afterwards.
