Header and H1 resizing errors when on smart phones, and icons

Hi.

Firstly, thank you – I love this theme. I’m having a few issues I hope you can help me with:

- With the header and footer phone numbers they are wrapping on two lines when viewed on smart phones

- H1 big_title is also not resizing properly on smart phones

- Icons are causing errors on home page. When I change the icon to “briefcase2″ or any others, the page will not load.

- Can I change the colour of the accordion toggles?

I would be grateful for any help. My domain is maternitycoaching.com.au
