I just got my IPhone 4 the other day and I jailbroke it and I tried downloading Updatr from cydia to update my cracked apps, but when I open it it opens for a few second then immediately closes. I rebooted the phone RIGHT after I downloaded it, I synced it with my pc, I also even deleted it and reinstalled it several times hoping that it would work each time...I don't know what else to do someone please help!!
