I think I can confirm this. I never got a fix with the internal antenna before - EVER! Now, having removed the microsd card and holding the freerunner out of the window, AGPSUI got the GPS time after ~18s, and TTFF was 111s. Amazing! Now, how do we fix that? ;) Regards, Konstantin _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
