Owners of Samsung Galaxy S, too much time to get a GPS Fix? No problem, GPS Aids will help you. You have two modes: native and forced (this last need a rooted device). The native method use a hidden option to inject into the GPS chip the XTRA data, it sometime fail, but actually it's working at 98% of devices. The forced method, simply download a file to your SD and then copy it to your system folder (you need root and BusyBox).
