Message formats looks terrible on iPhone

Hi all:

My emails look great on a PC. I look at them on my iPhone and the text is beginning to the right of the image instead of below it and the distance between the rows of text is not far enough so the lines slightly go over each other.

Any ideas?

@square1 You probably need to use a responsive layout. See and also the link to the Zurb templates.
This level of CSS is way over my head though.
