Review: HTC Freestyle
The only social networking option available on the Freestyle is HTC's Friendstream software. It offers about the same experience as what's available to HTC's Android devices. Users can sign into their Twitter and/or Facebook accounts, and Friendstream will pull down status updates.
Users can easily send off their own status updates to one or both services, as well as send replies and direct messages to Twitter contacts. You can also view (in a limited fashion) other users' Twitter and Facebook profiles. The application looks good, but still manages to be a bit on the slow side. it offers just enough Twitter features, but definitely falls flat with the Facebook portion. For example, it doesn't support Facebook messaging, only status/wall posts.
As far as catch-all social networking options go, Friendstream is one of the more pleasant to interact with.
