iOS facebook connect feed on wall

I am trying to post a feed on the fb wall using a new application with a certain API key, It's not posting anything on the wall, I have tried the same thing with another API key(other app) with the same settings and permissions of (publish_stream) and it worked (still working in a 10 minutes time difference between post and another wich is weird as well)

using this simple code:

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"some text", @"message",
                                   nil];

[facebook requestWithGraphPath:@"/me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

Any Idea?!
