There is an "add instant message" button in the Contacts application. There are some predefined ones like Skype, MSN, Facebook, etc but you can add a custom one.
However, if you add a custom instant message address, and use the ABPeoplePickerNavigationController
to retrieve the information, the servicename is always one of the predefined values (like Skype, MSN, Facebook, etc) instead of the custom one you have added.
This feels like a bug to me. Has anyone else seen this issue?
