I am using Flex with ADEP data services and robotlegs framework for my application. In the android device, I noticed that the dataservice is not disconnected when setting the device into airplane mode when using 4G network. The debug messages indicate the network status changed but not channel disconnected. The same problem exists in the iOS device but kind of inconsistent. I could not debug the iOS application on the device as I have no clue how to debug it for offline scenario. I read that the iOS debugging on device uses network and not USB. Correct me if I am wrong and let me know how to debug the iOS device over USB. I also posted a question for that in flex forums.
