I found out the hard way that you cannot root the "official" gingerbread OS via superoneclick. The method I used was to root it through the Rogers Infuse method found here:
[How To] Root the Rogers Infuse 4G - NOT for AT&T Infuse owners
The reason it says it is not for AT&T owners is because this was before AT&T gave us the official GB OS. Now that we have it, this is the method to use (for now). I followed this method and had no problem at all, and am running Zeus 5.2 Just make sure you follow the instructions. Since I was not rooted yet, I backed-up everything to my computer first. I created two folders on my computer as back-ups: one for my internal SD card, and one for the external SD card.
Many thanxs to gtg465X on XDA for this!!!
