Simple iPhone app as follows:

- Main screen, contains a logo, some instructions, and a large button
- When the user clicks the large button, their current latitude/longitude, and deviceID is sent to a server via JSON (server software not part of this job/bid)
- The server will return 1-6 nearby locations. The user will choose one, and the choice sent to the server
- the screen will change to a "confirmation screen" which includes a "cancel" button.
- if the user chooses "cancel", a "cancel" message is sent to the server.

if the user leaves the app on the "confirmation screen," when they return it should still be at the "confirmation screen".
