Did you get the blackberry used? If so it probably has an IT policy from the previous person's company he/she works for. You can look at this to remove the policy. Remove IT Policy - BlackBerryFAQ
As for not able to upgrade the OS it might be because of the current IT policy, although I could be wrong. Did you download the correct OS for your blackberry? It says you have an 8320, if so you should be downloading this one, http://www.blackberryforums.com/gene...languages.html
. Follow the instructions on that thread and you should be able to upgrade it.
