I have a scanned PDF document on an iPad 2 (iOS 6) that I need to rotate but cannot find any easy way to do this. How would I engage such an endeavor?
A lot of PDF viewers on the iPad allow rotation of PDF files. An example would be GoodReader which is a good app to have anyway if you need offline access to PDFs etc. To open a PDF in GoodReader e.g. from Mail use the "Open with..." button.
