iPhone Memory Leak JSON Library

Question

I'm getting an instruments Memory Leak with this iPhone 3.0 SDK code.

I'm using the JSON from http://code.google.com/p/json-framework/

Here is my code:

// .h
@property (nontatomic,retain) NSMutableArray *tweets;


// .m
import" JSON.h"
@synthesize tweets;
...
    tweets = [[NSMutableArray alloc] init];

    NSURL *url = [NSURL URLWithString:@"http://www.someurl.com"];
    NSString *jsonString = [NSString stringWithContentsOfURL:url];
    NSArray *results = [jsonString JSONValue];
    NSArray *data = [results valueForKey:@"stories"];

    for(NSDictionary *tweet in data) {
     TweetmemeData *tweetmeme = [[TweetmemeData alloc] initWithTweet:tweet];
     [tweets addObject:tweetmeme];
     [self debugDump:tweetmeme];
     [tweetmeme release];
    }
    [results release];

    return tweets;

If possible, please explain more about this form of memory management. I'm very familiar with retain/release but obviously am having trouble implementing it :)

Thanks!

It's worth noting that many leaks that will come up in the simulator don't happen at all on the hardware. Are you using the simulator or testing it on the phone?
