Other carriers are working on their LTE (Long-Term Evolution) networks, but in the meantime, the fastest speed can be achieved with Sprint smartphones and other Sprint mobile devices.
Both of these smartphones take advantage of the new 4G LTE (Long Term Evolution) network from Verizon, offering some of the fastest wireless data speeds available today.
A competing 4G wireless technology that will coincide with GSM-based providers is something called LTE or Long-Term Evolution.
Using more intense applications over the 4G LTE connection will likely shorten the battery life even further.
As expected, the Thunderbolt features 4G LTE, WiFi, and Bluetooth, but it does not have HDMI output.
As mentioned above, the DROID Bionic is capable of using the 4G LTE network.
For now, the developers are looking toward an LTE launch some time in 2011.
