iPhone in-app purchase screen shot

I provided a screenshot of the Confirm Your In-App Purchase dialog that StoreKit presents when purchasing each product, and everything was approved by Apple the first time. I didn't show screenshots of how the app changed before & after the IAP, so it doesn't seem as though this is required.

Here's one of the screenshots I used:

I have provided an image of the dialog I present to the user when I ask them to confirm the purchase...and it was accepted

Quoted directly from Apple's In App Purchase Guidelines

For review purposes only. Your In App Purchase screenshot will not display on the App Store or on the iPhone device store. Once you have tested your In App Purchase and are ready to sign off, upload a screenshot of your In App Purchase in this section. The screenshot should be a clear picture of your In App Purchase in action and must be 320 x 480, 480 x 320, 320 x 460, or 480 x 300 pixels.

Cheers.

UPDATE

The correct size is now 640 x 920. The other sizes are no longer accepted.
