Application for iPhone OS X

We need an application for the iPhone OS X. On the one hand this application should get the GPS-data from a (fixed) mobilphone and on the other hand show this GPS-data and the own GPS on GoogleMaps.? ## Deliverables Once more: The application has to run on an iPhone with OS X (including the new version of OS X). The application? should get GPS-Data from another (fixed) mobilphone (OR: an internet server, which asked the fixed mobilphone for GPS-Data). This GPD-Data from the other mobilphone has to be shown with the own GPS (from the application user) in GoogleMaps. This operation should retrieved ever three minutes. So the application users can every three minutes see there position and the position of another (fixed) mobilphone. German speaking experts welcome!!
