OS 6.1

With the new OS 6.1, the dual GPS apps "work" but my Ipod are unable to locate my. On OS5.1 every things work well but as soon as I upgrade to 6.1, I can track GPS Satellite , I know my position on Lat/Long But all those data arent send to my others apps. Its like if the ipod dont reconize the the GPS as e positionning device...
