"All from My Mac" in Calendars and Contacts
So, this is more of a fine tuning question than anything. I set up my iPhone 4 as a new phone, then synced all my contacts and calendars to it. I've noticed that the highest grouping in both apps in "All from My Mac". Now, I've created contacts and events on my iPhone that weren't on my Mac, but everything's still under "All from My Mac." Why aren't the data created apart from the Mac put in another group, or in a "All Contacts" or "All Calendars" group? Should they be?
