The all-in-one IM client, Trillian, is landing on Android in a big way. This new beta version of the application will soon be available for Android devices running version 1.6 of the green fiend and up.
If you have not come across Trillian before, then you probably do not send too many IMs. Trillian allows you to log into one program and chat through Yahoo, Google Talk, Windows Live, Facebook, AIM, ICQ, Jabber/XMPP, and MySpace IM. It organises all your contacts and makes the whole thing quite easy. I used the windows desktop PC version many, many years ago, so the company has been hanging around for a long time.
Another noteworthy feature, aside from contact sorting and grouping, is tabbed chatting. This is displayed in the picture to the right. If you want to be one of the first to get the application for Android then you should sign up here. It is scheduled to land within a few weeks.
