Apple Doesn’t Like the Tridentine Mass?

I just ordered a new iPod Touch. I took the engraving option, and asked for this to be inscribed on the back:

et cum spiritu tuo

But Apple refused to honor my request. Here’s the message I received:

“Inappropriate message text.”

So, instead I ordered this to be engraved on the back:

Lord Jesus Christ, Son of God,
have mercy on me, a sinner

It does have the advantage of being a bit more ecumenical than my first choice.
