Keith, the names have never ever been "switched", where did you get that from?
Iceland has always been called Iceland, for like, 1000 years.
No pam, I'm not - but I have friends in Iceland, and learning the language and so forth.

History of Iceland - Wikipedia, the free encyclopedia
According to Landnámabók, Iceland was discovered by Scandinavian sailor Naddoddr, who was sailing from Norway to the Faroe Islands, but got lost and drifted to the east coast of Iceland. Naddoddr named the country Snæland (Snowland). Swedish sailor Garðar Svavarsson also accidentally drifted to the coast of Iceland. He discovered that the country was an island and named it Garðarshólmi (literally Garðar's Islet) and stayed for the winter at Húsavík. The first Scandinavian who deliberately sailed to Garðarshólmi was Flóki Vilgerðarson, also known as Hrafna-Flóki (Raven-Flóki). Flóki settled for one winter at Barðaströnd. It was a cold winter, and when he spotted some drift ice in the fjords he gave the island its current name, Ísland (Iceland).
