NSData initWithContentsOfURL reading not all data, but only on device

I am banging my head about an issue I have on iOS7 development. I use the following piece of code to load an image from a webserver: 

    NSData* data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://someServer/someImage.jpg"]];

This works like a charme in simulator, reading exactly the 134185 bytes that the image has. Creating an UIImage from that data works as intended. Once I test the exact same code on a device (iPad Mini, iOS 7.03), though, it just reads 14920 byte from the same URL. Needless to say that I can't create an UIImage from that data then, creation fails and returns a nil. The read does not produce any errors (no console output, and also using the signature with the error output param returns nil here). Is there anything I missed around this rather straightforward task? Haven't found anything on the web on this…

Thanks, habitoti

So you don't have any error, and something is downloading. Maybe try to read this response and post here (I guess it is html/text body)?
You can use NSString method:
+ (instancetype)stringWithContentsOfURL:(NSURL )url encoding:(NSStringEncoding)enc error:(NSError *)error;

Can I suggest you use a library like SDWebImage to retrieve your image, it caches it and downloads the images asynchronously.

It also has a category for UIImageView so you can just call [imageView setImageWithURL:]; and it will load the image in when its ready.
