you can get call tones on the pro, however if you had them previously it will not swich over, via sn swap, if you just got the phone
cimple fix is to call sprint, or chat online with them, tell them the tone you want and they would be more than happy to set it up for you
it's kinda confusing with the digital lounge, because the pro isn't quite up to par with the sytem yet, it tells you actually you can't at the moment but you can, that error will be fixed in the near future.
