A little over a year-and-a-half ago Rock your Phone pioneered the iDevice unofficial store scene. Of course, Cydia had already been running back then, but at the time Saurik hadn’t yet implemented a central purchasing system. As a result, developers had to rely on themselves if they wanted to charge their customers for using their products. And here’s where Rock your Phone came in, creating the first true unofficial store for iDevice applications to be sold through. Later, Saurik followed up with implementing sales support in Cydia Store and ever since there has been a sort of cold war between the two, with developers choosing one or the other to post their products. In the interim Rock your Phone released Rock - a Cydia alternative, boasting some nifty features, including superior performance and the ability to backup your installed apps.
Well, in a recent surprising announcement Cydia is acquiring Rock, making itself the single place to turn to to get your jailbroken apps.
