mobile phone

I have to integrate a Drupal 7 site with a custom iPhone app. I need to be able to be able to perform the create, retrieve, update and delete process on the Drupal site using the iPhone app.

I have 20+ content types each with multiple custom fields. So what I need to know is will I have to write my own custom solution or is the Services module able to perform most/all of the functionality for me?

I am trying to make it easier for customers to send directions to a phone off of a website. Is there any new technology out there that can help with this? I have been reading on drupal and I have found that you can send phone to computer but I have not heard of anything that does computer to phone technology.
