But third party login is only working for flash, not for mobile. also still i can't get friend list to work with that. waiting for a update with solutions for above problems.
Could you try in the iOS simulator and check for the log messages when you try to login with thirdparty?
As for the friends list, you will only get that after you successfully logged in to fb or g+.
MdotEdot mentioned that the browser MAY open in the background when you try to login, so you'll have to hit the home button to view it. ThirdpartyLogin could also work if you're already logged in a social network, and you could check that with the log viewer and the simulator.
Unfortunately I can't test myself due to the Stencyl licence I have and the lack of a device
