Hi Saua, OK it's good to know that 5.1 works with your 8800. However with mine it does not and the log shows the following:

11.24.40 o [API] JSR-179 available

That's it. The main screen says "nothing to report, yet".
The TeleAtlas app finds satellites immediately, as do the 4.x releases of BBTracker
