I wonder...

Usually, when calling a store or business HQ, you're presented with the following:

To order or reserve a product, press 1.

To contact technical support, press 2.

To seek an in-store representative, press 3.

For all other questions, press 5.

...wait! What happened to four? Is it a secret party line or something?
Maybe apple's full of socialists and four is their primary root number for telephone calls...

Just a thought.
