I am having problems updating my old Superuser 18.104.22.168 to the new Superuser 3.0 from the Market. It tells me that there is a sign error or something like that when the app is trying to install to my phone. I was wanting to know if I can delete my old Superuser and then install the newer Superuser without any problems or will these cause me to lose root? Is there another way to get this app to update like clearing the data from both the Market and the old Superuser app? Thanks in advance.
