Call and Internet at the same time ???

[prboy1969]

Help !!! So I have a Sprint Touch Pro 2 running the stock Rom WM 6.1 . I want to be able to make a call and surf the internet at th same time . Right ow I can't . I know someone who has an HTC Tilt 2 (TP2) , and he can be on a call and surf the net at the same time . So i know it's not a phone issue , more of a Sprint blocked it issue . Does anyone know how to fix this ?
