Convert Simple iPhone App to be a proper iPad App

Convert simple iPhone App (which runs on iPhone and iPad) to be a Universal iOS App that will also show under iPad Apps in the App Store. Relatively simple App written in Xcode with some html data files. The App needs either (i) to be translated int a Universal iOS App for iPad/iPhone, or (ii) to be converted to a separate iPad App - options to be discussed. Not a huge job but needs to be done properly by someine with the right skills. Expert in Xcode and iPhone/iPad App development required. Possibly to work onsite in Central/South West London, possibly at your site. People based in London area therefore preferred.
