We are looking for an experienced iPhone app developer to implement our small team's latest reference-tool app concept. The developer must be familiar enough with all relevant aspects of the iPhone SDK to deliver a functional app prototype within 4 weeks after receiving our specifications.



The first core app functionality involves retrieval of remotely-stored data that can be sorted and displayed based on our specifications. We will provide all of the data, separated into the relevant fields.



The second core functionality uses the iPhone's GPS capabilities. We will provide the polygon GPS coordinates for up to four overlapping geographical areas; the app must return the user's location relative to all four areas, and present the remotely-stored data (mentioned above) relevant to that location.
