Lately too many phones have been lacking in the functionality of being able to use both data and voice at the same time. Although many phones have been unable to do this in the past with the technology we have now our phones should be more than capable of keeping a call while surfing the web. I know that this would be an especially good feature for people whom work in business and need to check data while on a call. Although Verizon does not advertise this on it’s flyer for the HTC Thunderbolt, since not all devices are capable of this and they don’t want to guarantee that this function will work if it might not. We all know however that this means it has the capacity to, but they would rather not deal with complaints if it does not work 100% of the time.
