I've two issues with Facebook Connect:
1) I use the new Single Sign On Authentication. It works great, but the first time, I authenticate an user with my App when I request the token, i immediately want to post a link to the users wall, but then I get this error:
2011-10-11 15:42:44.831 [1717:707] Dialog DidFail With Error: Error Domain=NSURLErrorDomain Code=-999 "The operation couldn’t be completed. (NSURLErrorDomain error -999.)"

The second time I try to post something to the wall I get a success, there I don't need to request the permissions again. But the first time it always fauls. With the facebook.app installed, but also with the redirect from Safari.
