I'm exploring using Flash Lite 3.0 on an E71. When I try to read an xml file off device, I get the prompt that Flash wants to access the network. I confirm this request. I am then given a list of options (AT&T Internet, AT&T MEdia Net, AT&T MMS, my own WLAN). I have tried all four choices. No matter which one I choose, I am returned to the home screen.
The FLA is published with Allow Network Access on, and functions fine in a desktop player. A crossdomain.xml file is in place.
