Hi, When I try to install the symbian_ua.sisx on the device (3rd Edition, FP2) then I get an error, which says, "Unable to install a protected application from an untrusted supplier". However, I'm able to install symbian_ua_gui.sisx (but the app doesn't work for some reason). Any has any clues over here?
