Iðunn

But...how is it pronounced?

I find the site's suggested root words for this name interesting. If "Iđ" means "again," one can take "again" and say it as "over and over again"... "continuous"... "never ending"... "everlasting." And "unna" is stated to mean "to love." Perhaps "Iđunn" can mean "everlasting love." She is the goddess of immortality and spring. What if the Old Norse, when coming up with this character, meant to say that everlasting love brings life and can surpass death? This is why I love this name.

Personally, I think Iðunn sounds much prettier than Idun, or any of the other related named that replaced 'ð' with a 'd' instead of a 'th' diphthong. Maybe I could add Ithunn to this site.
