I'm sure some of the people here would benefit from this, probably more so since its targeted at developers.
PHP Manual is the PHP.net manual, stored locally and fully searchable on the iPad. It lets you search the entire function list, browse the manual, and all the inline links work to take you to related docs. You can also bookmark documents, there is a session history navigation, and a persistant list of your last 50 viewed documents. Not to mention all the documentation has been themed to look nice on your shiny iPad screen.
I'm working on an iPhone version too, along with improving the menu navigation structure for the manual tab. Check it out, tell me what you think. Reviews/Ratings also appreciated.
