New address book entries on iPhone does not sync to iCloud I have an iPhone (iOS 5.1). I added a new telephone number to a new address book entry yesterday and today I find that neither the iCloud Web interface nor my address book on my desktop (OS X 10.7.3) know anything of the new entry.

I was used to automatic syncing via the Internet from MobileMe. Does it not work like that with iCloud?

(Calendar syncing appears to work. Both calendar and address book are switched on on both the iPhone and the iCloud control panel on my desktop.)
In your Macintosh Address Book, go to Preferences/Accounts and make sure that iCloud is listed there and enabled.

After doing that go back into Address Book and Click on the red bookmark so you're looking at the front page. It should say "iCloud" at the top of the list of folder/groups you may have there. If it says "On My Mac" then see if you can choose "iCloud."

The design of switching between "on my mac" and "iCloud" is confusing for us "old" mobileme users and my guess is it will change in time.
