Confirmed - on 10.3.3, [NSData dataWithContentsOfURL:] will offer the 
server the choice of gzip encoding, but will not actually unzip the 
transferred data before returning it to the client.  This is an 
unfortunate (and unexpected) change in behavior from 10.2.x.  You can 
workaround by calling +[NSURLConnection 
sendSynchronousRequest:returningResponse:error:] instead; this will 
also offer the server the choice of sending gzip'ed data, but will 
unzip the data before returning it to you if the server sends the data 
zipped.

Sorry for the inconsistency,
