text message authentication for iOS applications.
It is way over built and thus buggy. I wanted to Use Core Data, even though complete server side authentication is most advisable for a scinereo like this. The server authenticates and stores values in core data which it polls for user authenticaiton. It prompts for your phone number, sends a text message with a confirmation code which is entered tieing the phone number to the phone in a way allowed by apple. It also prompts to pull user contacts requeting permission from the client. All Information is stored in mySQL database.
