HTC Sense Mobile Experience
With the next generation of the popular HTC Sense mobile experience, the HTC ThunderBolt 4G automatically delivers your most-wanted information to your screen. It offers even more ways to stay connected–including FriendStream, which delivers Facebook, Twitter, and Flickr updates in a consolidated view. And you’ll be able to pinpoint the location of a lost phone on a map, send a command to make the phone sound an alert–even while on "silent" mode–through the htcsense.com web site. If needed, you can also remotely wipe all of the phone’s data with a single command in addition to forwarding calls and text messages to a different number.
Video chat capable over 4G LTE and Wi-Fi (see larger image).
