Review: HTC EVO 4G LTE for Sprint
The EVO offers 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 EVO 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 within other applications more easily. Twitter and Facebook are also both preloaded on the EVO as individual apps.
Other messaging and social networking tools include Google+ and Google+ Messenger, Latitude, and FriendStream. Each has its own widget or home screen shortcut that makes the app/service easier to access and use directly from the home screen panels.
What I like most about all of these is the sheer volume of options and ease with which most of them work. It takes only a few taps to create posts or messages from pretty much anywhere in the operating system.
