Pretty much that.
I'm about to buy my IOS license.
I already know how to use the iphone SDK since I have written my own apps in the past, but can i call my libraries and make api calls to the store kit, coreLocation, ect. With an basic IOS license ?, Without having IOS pro license ?
Thanks.
Check the license matrix here:

The plugins feature is enabled for Unity Pro and any mobile (iOS/Android) license, pro or basic
The documentation for plugins is here if you want to see how it'd work:

Have a look at: http://www.tinytimgames.com/2010/01/10/the-unityobjective-c-divide/ The bolg post shows a technique that uses KVO and the PlayerPrefs to pass commands from unity to objective-c.
