Simultaneous voice and data on the Sprint Evo 4G

Sprint. Simultaneous voice and data. Two things that, until now, have never gone together. But with the HTC Evo 4G (we've mentioned you can get it June 4 for $199, right?), it's finally a reality, bringing it in line with AT&T and T-Mobile. (If you're wondering what the holdup's been, it's a technical thing.) There is a caveat, however: Simultaneous voice and data only works over 4G and WiFi. So if you're in a 3G-only city, you're out of luck unless you're on WiFi. But it's better than nothing, and it's long overdue, and it's demoed after the break.
