Yesterday we heard from HTC, manufacturer of the Evo 4G, about the Android phone's capability to do voice calls at the same time as data. And as a quick follow-up, Sprint just pinged us on Twitter to clarify things on its end. The Evo 4G will do voice calls at the same time as you're connected over WiFi and not when you're connected over EV-DO (3G).
That's par for the course these days on any CDMA carrier. WiMax is a brand-new ballgame, however, and Sprint says they're still testing things, and that simultaneous voice calls while using data over WiMax is to be determined. That lines up with what HTC told us. It's not a hardware issue, it's just a matter of getting it to work, and getting it to work properly. So godspeed, Sprint. We've got faith in ya.
