Problems with font color on iphone, contact form 7 (jollyness theme)

Hi, I am using contact form 7 for my website. The theme I am using is jollyness and is apparently the rare version of it that can be used with wordpress. Anyway the message portion of the contact form is a white font on a white background, so basically not readable by person who writes it.
Any suggestions?
I managed to fix a similar problem on the desktop version by going in and messing around with the Custom CSS in “appearances” on WP admin.
As I said it is only a problem on the iphone…any suggestions would be appreciated! Cheers…
