This is my second time posting this because I have still not found out the issue. I currently have an iPhone 5 with iOS 7, and need to sync the contacts currently on my iPhone to iCloud in order to transfer to the new iPhone I have received. For whatever reason, the contacts are not being transferred. I would like to note that I have the "Contacts" option ON, as well as have gone through the following process without success: If all of your contacts do not restore: a) Go to Settings -> iCloud -> Contacts, and set contacts to "Off". b) When asked about your existing contacts, select "Keep On My iPhone". c) Exit to the home screen, then navigate back to Settings -> iCloud -> Contacts, and set contacts to "On". d) When prompted to merge your contacts to iCloud, select "Merge". I have heard that this has proved to work for some, so if anyone hasn't tried this yet, give it a go! As for myself, if anyone has an answer to how to sync my contacts from my iPhone to iCloud, please let me know. I am also eager to hear any other programs or ways to back up my iPhone contacts to my Mac or PC. I would prefer to be able to use iCloud, but if that proves to somehow not be possible, simply having the numbers backed up in any way would certainly suffice.
