I got this to work!

The following is the complete code.
All the authorization and data is supplied by the .xml test file that I have stored within the App bundle.

Thanks all!

=========================

- (IBAction)startSOAP:(id)sender {
    NSLog(@"\n startSOAP start");
    // create the request
    NSError **myError;
    NSHTTPURLResponse **serverResponse;
    NSData *serverData;
    NSDictionary *headerFieldsDict = [NSDictionary
            dictionaryWithObjectsAndKeys:@"Apple iPhone",@"User-Agent",
                                      @"text/xml; charset=utf-8", @"Content-Type",
                                      @"soapAction",@"SOAP_ACTION",nil];
    @try {

        // 1) The Request String.
        // Note: smsXMLString contains the entire SMS SOAP envelope, without the <? XML declaration command >.
        NSString *smsXMLPath = [[NSBundle mainBundle] pathForResource:@"sms" ofType:@"xml"];
        self.smsXMLString = [NSString stringWithContentsOfFile:smsXMLPath encoding:NSUTF8StringEncoding error:myError];

        // -----------------------
        // 2)  Create the request.
        NSMutableURLRequest  *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:theServerURL]
                                                  cachePolicy:NSURLRequestUseProtocolCachePolicy
                                              timeoutInterval:10.0];
       
        // -----------------------
        // 2a)  Modify the Request from default 'GET' to 'POST':
        [theRequest setHTTPMethod:@"POST"];
       
        // 2b) Modify the Headers:
        [theRequest setAllHTTPHeaderFields:headerFieldsDict];

        // 2c) Sent the Contents of the Body to the SOAP/XML data:
        [theRequest setHTTPBody:[self.smsXMLString dataUsingEncoding:NSUTF8StringEncoding]];
        // -----------------------
        // 3)  Get Synchronous Data:       
        serverData = [NSURLConnection sendSynchronousRequest:theRequest
                                          returningResponse:serverResponse
                                                      error:myError];

        // -----------------------
        // 4)  Convert Synchronous Data into Human-Readable String (Unicode 8) format:       
        NSString *serverDataString = [[[NSString alloc] initWithData:serverData encoding:NSUTF8StringEncoding] retain];

        [[soapResponse layoutManager]replaceTextStorage:[[NSTextStorage alloc] initWithString:serverDataString]];
       
        [serverDataString release];
       
    } @catch (id e) {
        NSLog(@"\n**** EXCEPTION: %@ ****\n",e);
        self.statusLine.stringValue = [NSString stringWithFormat:@"*** Exception flagged: %@ ***",e];
    } @finally {

        NSLog(@"\n end.");
    }
     
       
} // end startSOAP().
