I had the sync issue solved initially by using gmail contacts via Exchange sync on my iPhone and the built-in "synchronize with google" via the address book on my macbook. (Actually synced with Yahoo mail via the address book as well; this 3-way sync actually worked fine). I switched to iCloud contact sync, because it has a richer data model (try to tell your 4S that a certain contact is your mom, and it would creation the relationship as "supervisor" or something). Now this creates a problem, because I very frequently add/edit contact in Gmail and I want that to sync to my phone automatically over the air, and pretty quickly. Is there something that will keep iCloud and Google contacts in sync, without losing the richer data from iCloud?
