The EVO fan blog Good and EVO is reporting that simultaneous voice calling and 3G data (SV-DO) is working on Sprint's HTC EVO 4G LTE. Some of you may be aware that unlike GSM carriers (e.g. AT&T), CDMA carriers (e.g. Sprint) are unable to serve voice and data over 3G simultaneously. So if you were on a CDMA device talking to someone, it would be impossible for you to connect to the internet.
HTC Thunderbolt, announced at CES earlier this year, may only seem like it's underpowered compared to the dual-core offerings, but according to a very early unboxing by someone named Michael, it's quite a beast with some very admirable features. I don't know how Michael got his hands on this device so early - perhaps he's a tester, a ninja reviewer, or a VZW employee receiving Thunderbolt training (I'm most likely inclined to side with the latter), but he does spill some interesting details that I've summarized below, conveniently mixed in with some specs.
