I just upgraded a 9000 that I bought from a friend to OS 5.0.0.509 from a 4.6 version. I made the upgrade without having a SIM in the device so it definitely did not have a data plan. Before installing the OS I did a wipe using BBSAK. Then used it to load the new OS. That might not have worked if I had tried to do the install using Desktop Manager.

I put my SIM in it to test and everything seemed to work well.
