Default [Q] cisco cius

Hey I'm new here i just got a cisco cius off of ebay. it was a great price and had great specs. the only thing i can not do with it is enable the unknown sources. i go to applications and the unknown sources is greyed out. it will not allow me to install anything the stock app store doesn't work. there is no android market on it so i am wondering is it possible to root it some how or flash a rom on it . i can't find anything about this on the internet it has android 2.2.
