The Sparrow developers have not announced the eventual launch of an iPad version of the application, but a tweak to be released in Cydia will allow us to run the application without problems on the 9.7-inch screen of the tablet. Developer of the tweak Sparrow+ will launch the weak that will allow us to run Sparrow on the iPad as well, and the change mainly involves restoring the graphics and menus to be displayed correctly on the entire tablet screen.
