Please can anyone help. I just bought a new blackberry bold 9000 but its a grey piece and is unlocked. By mistake i synchronized it with my earlier blackberry 7290 because of which the operating system of my BB bold has changed. I want to know if i do restore factory settings, will my blackberry be blocked. As its a grey peice i dont know what to do. what is the best way to make my bb bold function as i got it. ie. unlocked.

and once it's unlocked changing the OS or wiping it clean will not relock it
