Complete an existing iPhone App -- 2

The demo app has been developed on January of this year and it allows to organize and create media files. The files are associated to a person name/surname/id. An example array was inserted in the app, but now we need the APP to connect to a web application, sending a GET parameter (to be calculated upon our instructions) in the url to retrieve the needed json (already echoed by the web application). The App must also be able to open a browser calling a specific url with the GET parameter to perform an automatic login (on server side the web application checks the parameter and if it corresponds to the calculation, it will recognize the user and open the user session). Finally, when the user connects the iPhone to the computer, and navigates the web application, he/she will have an upload page available, with a standard manual "browse" php button -> here the user must be able to browse the media files in the iPhone, recognize the ones associated to the person by the app and upload them manually -> that is, when the media files are created or organized they must be placed/copied in a folder named as surname_name_id (these data comes from the json) so that the user can see the association also outside the app (suggestions on how to obtain this feature are very welcome). We work at UCT+2 (Rome time) and would appreciate collaborations that allow to chat during daytime.
