Just my input:

I have a Blackberry storm 9550 from Verizon that uses CDMA and GSM.  I had this phone unlocked and was able to use an ATT sim card on it with no problem.  I also unlocked my Blackberry 9860 model from ATT and installed a Verizon 4G LTE sim card in it and it would not take.  However, I place the Verizon sim card in the unlock Verizon BB 9550 and it recognized it and I activated it, now I placed it back in the Unlocked ATT BB 9860 phone and voila!   it working great!

Now I have two phone that can operate on both ATT and Verizon network.
