It's hard to believe that after 29 posts in this thread nobody linked to the
iCleaner Pro developer's Blog 🙄
He explains in black & white why he had to remove some features in the version available on BigBoss: because users were not RTFM and breaking some apps & other stuff.
Cydia > Search: iCleaner > Details:
Same info in Cydia > Changes > Updates > from iCleaner older than 6.3.0 so it's kind of funny that a thread with a Warning title is needed to spread the info.
😛
One post above mentioned installing the iCleaner Pro version using the deb but again exile90 explains that:
So it's better to simply add his personal Repo and download from it.
BTW iCleaner Pro works absolutely fine on my iPhone 3G iOS 3.1.3 & 4.2.1 and also tested fine on my friend's 3GS iOS 5.1.1.
Moral: RTFM! 😱
