Basically, I want to be able to click a button on my mobile site that will bring up my contacts list on my iPhone and allow me to upload a contact of my choice (.vcf file). Preferably looking for a solution with just HTML, JavaScript, and/or ASP.NET if possible, but am open to any possible solution. My desired solution MUST bring up my list of contacts on click if possible.

After further research, I have found that this is not possible from a web application on an iPhone. You can save a contact to your files and then upload it, however.
