Ok, this is weird. When i make changes on my iPhone, contacts are updated immediately on my mac. When i make changes on my mac, i know that changes won't take place on my iPhone till 15 minutes which is the lowest sync interval. I created a group for contacts on my mac and it has been half n hour and still no change on my iPhone. I've noticed a similar behavior before as well. If i add a new contact on my mac, my iphone does not get updated until i actually connect it via cable and sync it. What's the deal here? Am i supposed to make some changes on my mac or my iPhone to get this working correctly? On my iPhone i've already setup my .mac account to sync contacts, email and calendar via push. Anything else i need to do? Thanks for taking the time to read this. Regards.
