Ok, guys I am going to try to clear this up for everybody here.
The OP (Marke) is correct when he said he
WAS able to use 1x voice and data at the same time with speeds up to 124k. The technology at the time was using EVDV (Evolution Data/voice). The technology DID allow this at the time, however around 2005 carries switched to EVDO.
EV-DV, written in full form as 1xEV-DV, is a 3G
voice and data technology for CDMA networks. Providing both high speed uplink and downlink connections, it is none the less unused and has been dropped by its developer, Qualcomm, in favor of EV-DO networks around 2005.
So at the time when Cricket was using the EVDV technology this WAS possible, but again to answer your question is is not possible now with EVDO on your Touch Pro 2 or any other device running on EVDO networks!!!!!!
Case Closed..
