I have an iPad and an iPhone and I wanted to sync my contacts across those devices. I finally figured out how to do it. You need to have the same settings in all your devices regarding which apps the "Contacts" app is allowed to access. For example, on my iPhone, I had allowed contacts to access the "Facebook" app. But on my iPad, I did not have this enabled. Because of this, not all of my contacts on my phone were showing up on my iPad.
To sync contacts, I recommend that you do the following:
- Open "Settings" > "Mail, Contacts, Calendars" > Under "Accounts" in both iCloud and whatever mail service(s) you use (e.g., Yahoo, Gmail, etc.), switch "Contacts" to the "On" position. This will allow your contacts on your Apple device to sync with iCloud and your email contacts.
- Under the "Settings" menu, go down to where you see the apps such as Facebook, Twitter, Flickr, Vimeo, etc. If you want your contact list to reflect your contacts in those apps, press on the app, and turn the "Contacts" tab "On." Your contacts will now show all of your contacts in that app.
Note: 1) In my experience, you need to do this across all of your devices in order for your contacts to be sync'ed properly.
2) There may be some redundancies in your contacts now that you have done this. E.g., you will have double or triple entries of the same person but from different apps. I recommend linking those contacts together. This can be done by looking here.
I hope this helps.
