Well, how would anyone in here know this? I'm guessing not to many people have flashed that phone to that service. I would look on line for some Touch Pro forum that deals specifically with that device and ask there. You'll possibly have better luck finding someone who's done this.
There's a reason why these features don't work from carrier to carrier. Sometimes, the phone is built to only work with the original carrier's service. This way, you have to use them. Or, the feature only works on the phones of the other carrier, so you have to buy a phone from them. This is why Cricket's service is so cheap. They make money selling you a phone.
