I have virtually no clue what I'm doing so bear with the stupid question...

I bought one of those cheap crystalview tablets just to tear apart and try and see what could be done with it. Anyway, my question is - is it possible to Root these tablets? I have looked around but can't find anything. It is running Android 2.2 but I would like to upgrade it if possible. Detailed instruction would be great as I'm about as slow as 2.2
