I just got my Xoom about an hour ago, I really know nothing about it and haven't done much research on it yet. It has asked me if I want to update the system to 3.2. My question is, if I accept the OTA update, can I get back to a different build if I want to try to root it, install Tiamat ROM, etc.? Like a sbf, or whatever it would be called on a Xoom. I don't want to update to 3.2 and then be stuck on it and not be able to have any fun with my fresh out the box Xoom.
