Managing contacts on an iPhone using ActiveSync could use some work.
Bug -- One of the new features of SM15 is the 'iPhone' type for a phone number.
- On your iPhone, add/edit a contact
- Change one of the phone numbers to the iPhone type
- It immediately syncs to server as 'Home' over EAS.
This works fine with CardDAV.
Strange -- when you add a contact using EAS, it creates a bunch of empty phone slots in the web interface (doesn't happen with CardDAV):
Annoying -- using EAS, all contacts come into Smartermail as "Lastname, Firstname" even though they are "Firstname Lastname" on iPhone and when you add them directly in webmail. CardDAV doesn't do this.
