Ios – In App Purchase sandbox problem

currently I am developing iOS application, which needs In App Purchase.

As in many tutorials (like this: http://www.raywenderlich.com/2797/introduction-to-in-app-purchases). I've created new app in iTunesConnect, uploaded binary and rejected it. After that i added few in app purchase products. In next step I added Storekit to my Xcode project and after that I wrote this code in my UIViewController:

- (void)buyPressed
{
    SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObjects: @"com.mycompany.appliaction_name.levelpack",nil]];
    request.delegate = self;
    [request start];
    NSLog(@"request started");
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *products = response.products;
    for (int i=0; i<[products count]; i++) 
    {
        SKProduct *proUpgradeProduct = [products objectAtIndex:i];
        if (proUpgradeProduct)
        {
            NSLog(@"Valid product id: %@" , proUpgradeProduct.price);
            NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
            NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
            NSLog(@"Product price: %@" , proUpgradeProduct.price);
            NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
        }
    }

    for (NSString *invalidProductId in response.invalidProductIdentifiers)
    {
        NSLog(@"Invalid product id: %@" , invalidProductId);
        UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Apple connection error!" message:nil delegate:self cancelButtonTitle:@"CLOSE" otherButtonTitles:nil];
        [myAlertView show];
        [myAlertView release];
    }
}

And I still receive info that all my in app products have invalid product id. Today I've found this: http://developer.apple.com/library/ios/#technotes/tn2259/_index.html

And one important thing:
"Important: DO NOT upload the development binary to iTunes Connect until the application is ready for App Review approval. If the binary is present in iTunes Connect and it is not fully functional, App Review will review the binary and likely reject the development binary. Testing In App Purchase will fail if you or App Review reject your most recent binary in iTunes Connect. The workaround in this case is to upload a binary without In App Purchase features that can get approved by App Review. Once the binary is approved, resume testing the binary with In App Purchase features."

So I have to create new app in iTunes once again, or should I build and submit my app without in app purchase and when app will appear in iTunes develop new version with in app purchase?

Thanks for answers!
