This very popular app for iPhone photography and from the same developer as the popular 645 PRO app, has just been updated. There’s an iOS 5 bug fix in the review/share module as well as enhanced saving of TIFFs and MAX-Quality JPEGs on older devices.
This is a free update, if you have previously downloaded this app. If not, you can download it here. It retails for $0.99/£0.69.
