FBConnect updating status?

[jimmymacapps]

Im just wondering if anybody could help me out with trying to update my users status with FBConnect.

Im using the following code that will post on the users wall but not update their status:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"blah", @"name",
@"blah", @"caption",
@"blah", @"description",
@"blah", @"link", nil];

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[[appDelegate facebook] dialog:@"feed"
andParamsarams
andDelegate:self];

Thanks in advance for any help
