A fairly minor update was just sent to Apple a few hours ago.  Fixed in the update are:

• unread count issue when marking an item as read
• an odd issue that comes up when portrait only is set and you hold your iPhone sideways while navigating to the article view page

Edit: Just a short 21 days after we submitted the update to Apple version 1.73 has officially gone live in the App Store.  You should get update notifications in the App Store shortly.
