New China-based program Kuaiyong allows users to download and install Apple apps for FREE on their iPhone and iPad without jailbreaking.
Application download here (Just in case the author of the article is told to remove the link: http://www.mobilepoint.us/2013/01/kuaiyong-download-instruction-for-how.html)
Tested this application out.
All you need to do once you have downloaded applications using this Windows application, is you hook your iPhone or iPad up to the computer and press the install application button (not in English, its located on the far right of the download bar).
The article provides a decent run through.
Edit: Should be in: "Tech News".
