Erel, I think I`m having the same problem. Ping works fine, I can see the test page fine in both Mac and Windows browsers, Designer works fine and I can compile to the simulator. When I compile to the device the app never arrives there, even though the ide says compile successful and the debugger runs, I just get a blank white screen on both my ipad and iphone with the title "B4A-Bridge". I say I think its the same problem because I have the network 0.0.0.0 address in the compiler log as does Wave.
