While on a call today I noticed I couldn't get data through my wifi connection. The wifi icon turned white, instead of the blue good connection color. As soon as I ended my voice call the icon turned blue and I had data, so I know the wifi connection wasn't at fault. I had an HTC Thunderbolt before Vz replaced it with this Razr, and I'm sure I could do voice and wifi data at the same time. Is this something the Razr doesn't do? Or is there a setting I need to change?
