Like the others, mine never says "Connecting" when I hit the connect button in Live Mobile 2. I am just stuck on the main screen of live mobile with no response to any screen taps. It just seems dead, I can close live mobile fine. So it is not locked up.
Can't revert to IOS 5.1X, but if I can help just let me know what you need tested. I think the wire shark results point to that the program is not trying to connect. By the looks of it, i'd say that is spot on with out doing the test myself.
