How many times have you mistakenly deleted one of your Home screen bookmarks on your iOS device? If that has happened to you in the past, then you may want to check out this new jailbreak tweak called BookLock.
Unfortunately, the developer of BookLock felt that this functionality was worth a $1.00 on Cydia's BigBoss repo. A dollar for a tweak that features nothing more than a single toggle to prevent Home screen bookmark deletion? Seriously? My advice to you is to just be careful when deleting items on your device...
