First, you must have more patience than that. While we try to answer all questions quickly, answers within a few hours must be expected. We strive to have answers to all questions within 24 hours, max, but usually are much quicker than that.
As to your question, I investigating some more and found that mobile page tabs simply aren't supported. Please see the bug report from Facebook below:
developers.facebook.com/bugs/435173473172584/
You can't link to the mobile version of your Facebook Page tab. We don't set this restriction, it's a Facebook limitation.
I hope that helps,
Alex
