iComic is a native iPhone application that allows you to read comics, manga, etc… in .zip format. The application is available via the developers site but only with Japanese menus. I’ve translated the menus to English for the people unable to read Kanji, Katakana and Hiragana. There are three different options for page turning. Gravity Page Slide uses the iPhone’s accelerometer to turn the page for you by just tilting your iPhone. Button Page slide allows you to turn pages by tapping on either side of the touchscreen to advance or go back a page while Swipe Page Slide turns pages using a swiping motion across the touchscreen. To get back to the settings menu while in portrait or landscape mode, tap on the upper left part of the screen. There are tons of comics, manga or books in .zip format available on the web so you’re best bet is Google. The files to be read need to be uploaded into the var/root/media/Comic folder of your iphone. The translated menus are available for download below after the screenshots and need to be unzipped. After unzipping, upload the entire Japanese.lproj folder into the Applications/iComic.app folder overwriting the original files.
