If only there was a way to add .cbr or .cbz files into newsstand, rather than simply in one of the comic apps. Sadly it seems that any file in newsstand must be added through iTunes in-app purchases; which means that if - like me - you buy your comics in a bricks-and-mortar store then download scans in order to read on the go, you would be unable to do so without purchasing the comic twice. I currently use an app called Simple Comic, which allows comic files to be added through WebDAV. As a comic file is merely a .zip or .rar containing nothing but images, the apps which display these files are very straightforward, it just seems a shame that it would not be possible to have them in the newsstand app. I currently read about 16 comic series, and it would be great to see them in with the newspaper and magazines that I read. Perhaps a jailbreak would able that feature at a later date?
