So, to answer the question with a summary of what all has been said, the BlackBerry 3G devices are: 8707 (GSM/UMTS), 7250 (CDMA/EVDO), 7130e (CDMA/EVDO), and 8703e (CDMA/EVDO). There *should* be a SureType UMTS device out shortly. And as NJ stated, the 8707 UMTS device is not compatible with the Cingular and Rogers UMTS networks running at 1900mhz.
So does this mean with Rev A you can do voice and data simultaneously.
