iv donloaded and installed os 6 for my 8520 of the net but my desktop manager wont find it. it does work because my friends runnin on os 6 for the 8520!
I have the same phone and I had the same problem, run DX.OS off a laptop connected to a desktop with an ethernet cord. Then search for system 32 AND MAKE SURE THIS IS DELETED BEFORE YOU GO ANY FURTHER or else your blackberry will be deactivated.
