Is it possible to serialize and store custom structs on the iPhone in scriptableObjects?

This is the general idea. I'd like to store a bunch of these in a scriptable object without making them classes. Unfortunately it fails to save the data when stored as a struct.

I've seen forum threads mentioning using custom inspectors, but those are not available in the iPhone IDE.

[System.Serializable]
public struct Point{
    public int x;
    public int y;

}

As a thought, if this IS possible in 2.6, how would one go about saving the data, and could that data be imported into iPhone Unity once serialized as an asset?
