So I just saw this tweak in Cydia and as most of you know if I see a useful tweak I make sure to share it with our readers. The tweak is called NoNewMark8 and it removes the blue dot next to the icon after you do a update for that app in the AppStore. All you have to do is just install this tweak and your done. 

So if you hate that blue dot get NoNewMark8 from Cydia.
