Create a manual backup in iTunes (by connecting your phone to iTunes, going to the Summary tab of your iTunes sync settings and clicking on Back Up Now under Manually Backup and Restore), then sync with iTunes. Then restore to your December iCloud backup. If your missing note is restored, email it to yourself (by opening Notes, tapping the share arrow icon, and tapping Mail). Then restore to the iTunes backup you made earlier to return the phone to its present state (by connecting your phone to iTunes, going to the Summary tab and clicking Restore Backup under Manually Backup and Restore).
