syncing calendar & contacts
When I add calendar items to my iPhone, they automatically go to my computer. When I add calendar items to my computer, they do not show up on my iPhone until I manually sync them. Contacts are never synced until I manually sync. Since syncing manually takes a very long time, is there an easier way for my iPhone and my computer to sync up?? I do not have iCloud, because I don't have a .me address (that I am aware of).
MacBook Pro, Mac OS X (10.6.8)
