The Infini Dev Team, who made Icy, have started working on a new project that will allow you do download Cydia packages from Safari on your Jailbroken iPhone, iPod Touch and iPad.
With “Lima” all you need to do is just go to safari and type in a URL and you get all the access that you would find in Cydia, such as Categories, Search and all the sources that you can add from Cydia, BigBoss, iSpazio, Insanelyi. You will be able to download and install the packages straight from Safari without using a secondary app. No install is expected to be required for this to work.
The ETA on when this will be Public is not released but all they say is “Soon” so stay tuned!
