Voice / Data Simultaneously?

[Mustang46L]

So, I'm remembering back in the day when I bought my first "Vision" handset and voice/data calls were only glitches in the system while they were doing beta testing and we were all told that we would be able to do that "someday". Later we were told that "someday" was nearing and it would be when we had EV-DO Rev. A (or B). So it appears that "someday" is here..

So my question is, once we get our software update on the Mogul, does anyone see the possibility of unlocking the software in the Mogul to allow simultaneous voice and data calls or are we all going to have to wait for WiMax?
