debugging iphone app and adding some features

We have a iphone app but it has bugs. The idea is that one should be able to shake a phone and the current location and direction? is saved in a online database. the app loads point in interests and checks if one approaches a point of interest. If it approaches a point of interest? at a distance of 1KM? a signal? is? going of and the? phone shakes.? An messages is shown with the type of? POI. Every 5 km a new list of POI is requested. At this time the poi are listed but that is not neccecary. The GUI should be cleand too. It is possibe that the poi does not have a direct. Then the signal etc? should be triggered even the direction is unclear but one is approaching the POI. The text should be different.? At this moment the app chrases when one? shakes the phone and when? one approaches? a poi.? We have a apple sdk account and a uptodate iphone. We do not have an apple though so we want to have betas via the beta test programmes for iphone apps using windows. Please have a look at the file
