How do you organize your personal and professional contacts - on your phone through iOS? MS Outlook? Other?
Distinction between personal and professional contacts has become very blurred in real life, at least for me, so no real difference in organization other than tagging where I know that contact from (e.g., company name, school, church, etc.) In the phone's contact information.
Friends are regular. Professional I'll do [companyName.Name] like "Barclays.John Smith"
