I tryed to run a Flash Lite application on N-gage but is didn't recognize the
file. It's said that N-gage supports Flash Lite so I dont know what's going on.
Do I need to install a flash player? If so how do i get it? do I need the Flash
SDK?

Hi,
you need the Flash Lite Player.
You can get it so:
you've write e-mail with your phone model and IMEI number to this address:
