Yes, there's a reason the iPhone won't do simultaneous voice and data over the cell phone network: 3G/CDMA technology is not capable of it.
And the Thunderbolt, when in a 3G/CDMA coverage area, won't be able to do it either.
Simultaneous Voice & Data is a 4G/LTE thing on Verizon. And it can be done on GSM systems.

taken "straight out of the VZW training":
There is functionality in the Thunderbolt that allows simultaneous voice and data while on the VZW 3G network, however, we cannot promise the experience will be one that is consistent with our brand. As a result, do not reference this functionality as a benefit during your conversations with customers.
i know its an lte phone... but i did not say voice and data while on 4g or the wifis...
phandroid and android-life both have it up... if u would like 2 c for urselves...

According to the link below, it's confirmed that the Thunderbolt can do voice and data on 3G.

I would not doubt that it has a seperate LTE/3G chip which allows it to do simultaneous connections.

There is a rumored revision to the 3G/CDMA standard that is said to be capable of simultaneous voice & data - and it's something that the phone has to be capable of doing. The current crop of 3G/CDMA - EVDO.REV.A phones can't do it, and the iPhone is one of those.

When you leave LTE coverage though it should be back to business as usual.

Thunderbolt will do Voice over 3G and Data over 4G in select coverage areas. Simultaneous Voice/Data over 3G won't be supported (despite rumors to the contrary.)
Verizon's 3G network could (read again COULD) provide simultaneous voice and data if Verizon were to apply a software upgrade to it's 3G infrastructure. The upgrade is costly since it means touching each unit so Verizon hasn't planned to do it. Devices that support EVDO Rev.B would be required (I'm most sketchy on this part.)
LTE does not have a voice channel but instead operates more like VoIP (or VoLTE.) Voice is treated like any other application on the phone so simultaneous voice/data is possible, but most current devices use a 3G radio to provide voice service. Verizon and others are testing VoLTE for the future. Supposedly the new LG 4G LTE handset has done VoLTE but until the LTE network is in greater deployment you won't see it in widespread use. Safer to leave voice to the 3G radio.
