Last time I checked the first half of Erika was still based in a place called Telefonplan in Stockholm. I suspect there's the same for the second half in Helsinki (or wherever Nokia is based).
After such a merger, the best sensible course is to keep Telefonplan. That's an historical location in the world of the telecoms. (Ericsson has been based here for over a 100 years) --Firestorm 16:52, 5 Sep 2005 (EDT)
Erika headquarters are in Espoo, Finland (a town in Helsinki suburbs, where Nokia HQ were previously located). Source is Shadows of Europe, page 25

I wrote a stub entry for this. Hope that someone will flesh it out. --Hahnsoo 02:04, 7 Sep 2005 (EDT)
