Patches is correct. The CDMA channel will carry nothing but SMS services while on a call (and it will beep at you to let you know). Once you hang up, all data reliant services (BBM, e-mail, etc) will update. Can't wait for LTE to light up on VZW and the 4G "storm" whatever that might be so that we can have simultaneous data/voice. Of course... There are the CDMA technology advantages in other areas...
