How to get friends' status updates from facebook with FB Connect for iPhone?

Question

Hello! This is my first question in here, but I've gotten loads of help from other posts in here, so thanks for a great community!

Ok, I've got my Facebook session set up and I'm able to log in and get my UID. But when I run this query, I get a blank result:

- (void)getUserName {
    NSString *fql = [NSString stringWithFormat:@"select uid,message from status where uid in (select uid2 from friend where uid1=%lld) order by time desc ", uid];
    NSDictionary *params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];  
}

Appreciate any help you can muster!
