SayText is a free OCR app for iPhone that recognizes text within a document and reads it back to you with VoiceOver. The app does not work as quickly as the Intel Reader but is fairly quick. The app is very simple to use and does not include a lot of features. Focusing the text in iPhone camera is hard and requires a steady hand. The app includes an automatic image capture feature when the text is in focus. Make sure the camera flash is on to increase the image and scan accuracy. SayText is free in the iTunes app store so there is no harm in trying it out.
