Review: HTC Droid Incredible 4G LTE for Verizon Wireless
The Incredible offers both individual and system-level messaging tools. The individual apps include the basic toolset from Android, such as Gmail, email, SMS, Google Talk, and Google Voice. These are all fine applications that continue to be useful for composing all sorts of messages. There aren't any other IM apps, so Google Talk is your only option out of the box.
In terms of social networking, the Incredible offers integration with Twitter and Facebook within the OS. Sign into your social networking account and you can do things such as share photos, or messages from inside other applications more easily. The separate Facebook app is preloaded on the Incredible, but the official Twitter app must be downloaded from the Google Play Store.
Other messaging and social networking tools include the newest version of Google+, Google+ Messenger, and Latitude. Each has its own widget or home screen shortcut.
