There's two types of attacks. One is a fake tower the other is just listening in/relay of signal to a real tower with out any funny business. The change T-mobile is making will help prevent the later but the downgrade attack will still work.
As long as the device supports the insecure standards the fake towers will work for downgrade attacks (assuming they prevent you from connecting to a better tower).
