I wonder how you just read that. I read:

My 'o-t&-mO-"bEl and 'mO-b&l phone allow me to be 'mO-"bIl. (pronunciation guide).

And I'm guessing that most Americans, excepting Southerners, would do similar. I'm also guessing that most English speakers outside of the US would not.

Why? I don't know the answer to that, Yaty, however I will agree that it is totally inconsistent.
