JSON POST Request on the iPhone (Using HTTP) Problems

Question

Im having problems with my request to a asp .net mvc web service. I read in a thread a while ago that its possible to find out what the server wants the the request's content-type to be etc. I get no error when compiling but when I do the actual request nothing happens and in the log of the server it only says (null) (null). There is no problem doing the GET request and fethcing all objects that are in the list. Can anyone please help me with this irritating bug? here is the code:

//----------------GET request to webservice works fine----------------------------------------
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: url];
[request setHTTPMethod: @"GET"];
NSData *response = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];
NSString *stringResponse = [[NSString alloc] initWithData: response encoding: NSUTF8StringEncoding];
//NSLog(@"stringResponse is %@", stringResponse);
//--------------------------------------------------------------------------------------------
NSString *twitterTrendsUrl=@"http://search.twitter.com/trends.json";
NSString *output=
[NSString stringWithContentsOfURL:[NSURL URLWithString:twitterTrendsUrl]];
id theObject=   [output JSONValue];
NSLog(@"TWITTER: %@",theObject);
*/
//--------------------------------------------------------------------------------------------

NSURL *url = [NSURL URLWithString:@"http://errorreport.abou.se/Errors/1.0"];



//NSString *jsonRequest = @"{\"Description\":\"Gurras Description\",\"Category\":\"Klotter\"}";
//NSString *jsonRequest = @"{\"Description\":\"Gurras Description\",\"Category\":\"Klotter\",\"Address\":\"smedjegatan\",\"StreetNumber\":\"34\",\"Feedback\":\"True\",\"FeedbackWay\":\"Telefon\"}";

NSMutableDictionary* jsonObject = [NSMutableDictionary dictionary];
//NSMutableDictionary* metadata = [NSMutableDictionary dictionary];
//[metadata setObject:@"NewLoc" forKey:@"Uri"];
//[metadata setObject:@"Location.NewLoc" forKey:@"Type"];
//[jsonObject setObject:metadata forKey:@"__metadata"];
[jsonObject setObject:@"Gurras" forKey:@"Description"];
[jsonObject setObject:@"Klotter" forKey:@"Category"];
[jsonObject setObject:@"smedjegatan" forKey:@"Address"];
[jsonObject setObject:@"34" forKey:@"StreetNumber"];
[jsonObject setObject:@"True" forKey:@"Feedback"];
[jsonObject setObject:@"Telefon" forKey:@"FeedbackWay"];
// ... complete the other values
// 
NSString* jsonRequest = [jsonObject JSONRepresentation];
// jsonString now contains your example strings.

NSLog(@"Request: %@", jsonRequest);

//NSURL *url = [NSURL URLWithString:@"https://mydomain.com/Method/"];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"json" forHTTPHeaderField:@"Data-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];

//[NSURLConnection connectionWithRequest:[request autorelease] delegate:self];

NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];

NSLog(@"returnData: %@", returnString);

I can also add an example of how to talk to the service with javascript:

<script type="text/javascript">
var obj = { "Description": "det kanske funkar" };
$(document).ready(function () {
    $.ajax({
        type: "POST",
        url: "/Errors/1.0",
        dataType: "json",
        contentType: "application/json",
        processData: true,
        data: '{"Description": "STeffeent   asdasd", "Category": "Miljö", "Address": "Bogatan","StreetNumber": "14", "Feedback": "true", "FeedbackWay": "Brev"}',
        success: function (data) {
            $("#result").text(data.Description);
        }
    });
});
