I have Bluefire reader on my jailbroken iPhone and iPad. Both crash SpringBoard when I close the apps. I have used the Backgroundr workaround that is posted on various forums online(e.g. http://www.mobileread.com/forums/showthread.php?p=1241275#post1241275).
However it's doesn't work. I know the developer stopped supporting Backgroundr. Is there other tools like Backgroundr that I can use?
