Verizon Wireless and HTC announced the HTC ThunderBolt amid a flurry of 4G LTE devices rattled off at Verizon’s press event. With all those devices jammed into one press release, there were bound to be some tasty morsels Big Red couldn’t fit on the page. Luckily for us, enthusiast blog Android Central has gotten its mitts on what is said to be an internal Verizon Wireless training document, and it includes an interesting note — the ThunderBolt will indeed support simultaneous voice and data where LTE service is available. That might seem like a foregone conclusion but unfortunately it’s not, as Verizon indicated during CES that not all LTE smartphones would support simultaneous voice and data.

Hit the break for the purported leaked document highlighting a few firsts for the ThunderBolt.
