Save to Contacts with 1 tap

[/>eathwish]

I use the following code on my mobile website to allow users to save my contact data in their contacts by clicking or tapping on a link:

<br /><br /><!--Goodie//--><!--PhoneBook//-->
<span class="underline"><a href="wtai://wp/ap;8005551212;John Doe">Add to your Phone Book</a><input name="tel_no" type="hidden" value="8005551212" /><input name="tel_msg" type="hidden" value="Add to your Phone Book" /><input name="tel_name" type="hidden" value="John Doe" /></span><!--PhoneBook//--><!--/Goodie//-->

It works great... but not on the iPhone. It seems to work on most PDAs & even cell phones. Does anyone know how to modify this code or any alternate code that would accomplish the same thing?

I am developing a site specifically optimized for the iPhone & it would be a shame if I had to exclude this feature on such an advanced pda/phone.
