new Array () crashes Windows Phone 8

I am using Unity 4.2.0f4, trying to build for windows phone 8. Nokia Lumia 620
The second I have the following command in place, it crashes the app.
Works great on iOS and android and I really love this array. What can I do?

js code

#pragma strict

var moves = new Array ();

function Start () {

}

function Update () {

}

Just apply the script to the camera, it will force close it the second it opens.

Probably not supported by wp .net.

You could use builtin arrays or generics as they are better for mobile anyways.

But Push and Shift are so nice :)
Thanks for the reply, will convert to builtin array.
