Can't upload a file

[dyaacov]

Hi,
I'm trying to upload a file from my iPhone ios 6.
In wireshark, I see that the data is missing, I only see Content-Disposition and Content-Type but no data.
Content-Disposition: form-data; name="file"; filename="mypic.jpeg"\r\n
Content-Type: image/jpeg\r\n\r\n
and after that - NOTHING

Here is my code:
RFRequest* r = [RFRequest requestWithURL:[NSURL URLWithString:url] type:RFRequestMethodPost bodyContentType:RFRequestBodyTypeMultiPartFormData resourcePathComponents:nil];

//add files...
NSData *data = UIImageJPEGRepresentation(self.selectedImage, 1.0);
[r addData:data withContentType:@"image/jpeg" forKey:@"mypic.jpeg"];
