I'm thinking you can load any OS of the same model to any carrier's phone. I've done it between Verizon and Sprint. But the catch is this... It will still load up with the native carrier's logos as well as the interface. Also, the problem you would run into with that is the fact that if you flash the Blackberry to US Cellular, US Cellular won't activate it because it's going to require the data plan for Blackberries and it won't work on the US Cellular network.
I hope I made sense on this one and I am not fully of poo poo. But that has been my experience.
