And Bermuda is part of the Caribbean so...
Since when? Has it moved recently? 
Could have, you know, with the triangle and all. I am not saying it was Aliens, but it was Aliens.
Ok, seriousness aside , I have tried Ice Cream, and the name is perfect, the flesh is very creamy smooth, has a strong flavor. last year I did get a couple fruit off my tree, but they were not as good as the ones I tasted off a mature tree, mine were extremely resinous, with lots of turpentine. it could be that it wasn't ripe enough, hard to tell with this variety as they do not get much color to them.
This year, the tree flowered but nothing held, as mentioned by others, its rather susceptible to disease, in my case, Powdery Mildew. but the tree is attractive, very small leaves, looks almost ornamental, I think it would be a nice tree to put in the front yard, can be kept small, and the greenish mangoes should thwart mango snatchers.
