Reason I ask - I have a customer who wants a touch screen phone (BlackBerry Preferable).
I know the Storm has a GSM slot but can I buy an unlocked phone and throw it on a non supported carrier? Would it work - Data and Voice?
yes it can be. just becareful the GSM connection on the 9530 is not 100% if she or he is going to use it with a blackberry data plan. the GSM/EDGE connection will come and go. what i mean by that is it will go from EDGE -edge the lower case edge = will not let you get your emails there is no data connection. if she or he is going to use it on att network the firmware that best holds a perfect connection was the stock firmware it came with .78 the GSM holds and does not drop. she or he will be happy then .
you also have a 2nd option by getting the 9500 which is the GSM only version thid model is perfect or even better then the 9530 due to the fact that you can update the OS and your connection will not be affected.
