I had noticed strange things with GPS... The Icon would appear and disappear from the status-bar. I would think that if I didnt see it .. then GPS was not enabled ... so I would go toggle it .... But It seems after the RC33 update the radio must not be active until an app requests connection ... If I place the GPS-using app in the background the GPS-Icon diappears for the Status-Bar ... and I believe you loose active fix ... when you return to the GPS-using app the Icon reappears ... but now has to re-establish it's fix again ... This is a not great for gps dependent apps ... But I think this may have been a boon for saving battery .... Anyone else with thoughts on the impact .... ???
