Thanks for visiting! I really appreciated the comments.
I found a great tutorial which may help you out.
Check out Integrate Drupal with iPhone
This really seems to be a helpful lead. I was able to download his iPhone app example. (You need to use git) and upload the various modules to my drupal website.
I almost got it working. I can get nodes to load, but the OAuth part isn't.
Using the Rest Server with OAuth, I think will be a great way of authenticating and even uploading files images etc.
I'll post more when I get this working...
