How to exclude iPads

How can I exclude iPads from the plugin?

I used to do this by going to:

wp-content/plugins/wptouch/core/mobile-user-agents.php

… and under TABLETS inserting:
‘iPad’

… but that page now says “Handled by the tablets module”.

But I only see anything that seems to be related to that in:

wp-content/plugins/wptouch/themes/foundation/modules/tablets/tablets.php

… and nothing I do there seems to make any difference.

In fact, I can’t see anywhere in the plugin settings that tells me which theme I’m using!

The reason I wish to exclude iPads is because Facebook’s in-app browser shows the iPhone-style mobile theme if I don”t exclude iPads.
