Twobile (pronounced Twoh-bul, a mixture of the words “Twitter” and “Mobile”) is a new Twitter client for users of Windows Mobile Pocket PCs that adds many of the features you’d get from a desktop Twitter client like Twhirl or Twitterific.

Twobile is free, but you have to pay to use Twobile for business purpose.The client allows you to update your status, view the public timeline, your friends timeline, send and receive replies and direct messages, view featured users and favorites. And you can view avatars when you click on an individual message.
