But, as noted by iDownloadBlog, the app has a nearly 92% piracy rate based on just under 200,000 downloads. That means that just 16,000 copies were legitimately sold, while the remaining 184,000 downloads were pirated.
Base on the above figures that meant that there approximately 16,000 copies were legitimately sold, ergo the dude made $47,480 (and probably more to come!)
However if he sold 200,000 legitimate copies then that would have been just under a cool $600,000.
Can understand why he is p!ssed off, could this be a conspiracy conducted by Apple to encourage the jailbreak developers away from the jailbreak scene?!
