The functionality of smartphone applications may be extended to a basic phone, i.e., a phone lacking a particular smartphone capability, by providing a data synthesizer in the basic phone that synthesizers required data points. The data synthesizer may communicate with nearby smartphones to collect relevant data points such as location or motion data. Data points for the basic phone may be calculated from the collected data points. When an application on the basic phone requests data, a data provider proxy may retrieve a synthesized data point from the data synthesizer. In one example, a basic phone without a GPS or similar location module may execute a mapping application by averaging location data from nearby smartphones.
