I'm looking for guidance. I'm currently testing a 3Gs and a Droid, and love them both. I've heard/read that I can't do both voice and data at the same time on Verizon's CDMA network, which would be a deal killer for me... BUT... I tested this the other day. I was driving down the road, not connected to any WiFi. I called my 3Gs so I could have a phone call constantly running. While on the call, I was able to check my email, and continue running the Google Navigation app (the voice instructions even continued, but simply came through the earpiece instead of the speaker since I was on a call). The phone call was a running process in the background, but continued to work fine (I'm sure I looked weird sitting at the stoplight with the Droid on one ear and the 3Gs on another). I DID notice that once I ended the email process and Google Nav app, that the "3G" appeared again in the top of the screen. So was I accessing some sort of lower level network on Verizon (like AT&T's EDGE?) in order to do both voice and data? If someone could explain how all of this works, that would be very helpful. Like I said, I keep reading that it can't be done, but my test seemed to work fine.
