Don't wanna make new topic so I'll ask on this.

I've just downloaded PL from app store. Wanna start Play but every time when I connect to server I'm disconnecting after 10 sec. I turned off everything what admin mention in this post, I'm trying play over my 3G, ping between 100-300 but still I'm disconnecting even with ping 100. On wi-fi everything is ok, just 3G doesn't work. And mostly I have time to play over my 3G than wi-fi, any ideas what can fix that?

iPhone 4 not jailbroken,
