Regularly syncing the iPhone with iTunes not only updates the device with music, pictures and other multimedia stored on your computer, but also backs up information stored on the iPhone onto the computer. If you use an iPhone 3Gs or iPhone 4, iTunes backs up "Notes" from the iPhone and stores them alongside contact information from the email address you configure as a source for back up contacts.
