Half of Input.acceleration in working

I'm making a game for both iPhone and web player, and I've got the side to side movement working in landscape mode on the phone, but tilting the phone up and down does nothing. Everything works as expected in Web Player.

Here is my JS code :

Code (JavaScript):

1. function Update () {
2.         if (Input.GetKey("right") || Input.GetKey("d") || Input.acceleration.x>0) {
3.             rigidbody.AddForce(floatSpeed,0,0);
4.         }else if (Input.GetKey("left") || Input.GetKey("a") || Input.acceleration.x<0) {
5.             rigidbody.AddForce(-floatSpeed,0,0);
6.         }else if (Input.GetKey("up") || Input.GetKey("w") || Input.acceleration.y>0) {
7.             rigidbody.AddForce(0,floatSpeed,0);
8.         }else if (Input.GetKey("down") || Input.GetKey("s") || Input.acceleration.y<0) {
9.             rigidbody.AddForce(0,-floatSpeed,0);
10.         }
11. }

 

Wow do I feel stupid. I changed all the else ifs to just ifs and it works perfectly.

 

Yea I'm not sure you can do that with movement. I've seen an issue like this before with multiple else ifs and the thing just wouldn't take.

Maybe switch case will work and be a bit more optimal?
