I have been upgrading latest OS's for as long I remember. I currently have the .174 on my bb 8900 and love it so much. I plan on updating it to .199 after I am satisified with the feedbacks given on it. I have deleted other OS's in the control panel program list, but not one is able to be uninstalled/removed. It keeps displaying "This action is only valid for products that are currently installed". What do I do? I think I was able to install newest OS with that one still in the list, but I'd like to have it removed. Any advise/tip? Many thanks.
