Was this the form http://www.jotform.com/51398224072252 you were having issue with Iphone browser? Currently it looks like this when I test on Iphone emulator
I suggest to also try first updating the form and apply the options described on the user guide
Adding the Mobile Responsive Widget on the form should also help.
Please try the suggested modification then check again.
Let us know if this did not work.
I made a test applying the -How-to-make-Forms-Mobile-Responsive
and it looks much better
