I've just found an online form builder that create mobile forms. Best part is, its free!
Here's the link (no aff): Lanbito: Mobile Form Builder
Currently they only provide link to the form you created and you can't embed or download the form.
I've created a few samples which you might want to scan and view on your mobile.
I'm using iPhone 3gs, so I'm interested to know how it looks on your mobile especially other brand of smartphones.
