I am maintaining an in-house ASP.NET web app, part of which includes a Customer Relationship Management module for our sales team. One of the things they want is to be able to export all their contacts out of our database into their wide variety of email clients (Outlook on Windows, allsorts on Mac) and phones (IPhones, Blackberries - probably Androids). vCard seems to be the standard way to transfer contact information, but...
- Is it possible to specify multiple contacts in a single vCard by concatenating the vCard BEGIN/END blocks?
- Is vCard import support uniform, or are there quirks between clients?
- Any other tips/tricks/gotchas?
