Review: HTC Vivid for AT&T
The Vivid offers no surprises when it comes to messaging applications and services. It offers the stock Gmail, Google Talk, SMS, and email apps. The stock apps all work well, as they do on other Android devices.
The newest versions of Facebook and Twitter for Android are pre-installed on the Vivid. HTC also tosses in its FriendStream application/widget but not its Peep application. FriendStream performs well. It merges all your Facebook, Twitter, and other feeds into one place and allows you to manage posts, or just scan what's going on. But it still doesn't replace all the functionality available in the full Facebook and Twitter applications.
Qik Lite for video chatting is on board. Google's Latitude app is on board; Foursquare isn't.
