The Verizon iPhone 4's inability to do simultaneous voice and 3G data is still one of the key differentiators between it and AT&T's GSM version, but it seems not all Verizon smartphones are created equal. According to a purported leak from inside the carrier and passed to Phandroid, the upcoming HTC Thunderbolt will actually support simultaneous voice and 3G data; however, it's not something we should expect to hear Verizon making much noise about.
According to the leak, Verizon "cannot promise the experience will be one that is consistent with [the] brand" and so are advising sales people to "not reference this functionality as a benefit during your conversations with customers." As sales strategies go this seems somewhat bizarre, but we can understand Verizon not wanting to overshadow its other devices - including the new CDMA iPhone - with a single HTC handset.
