Trillian is one of the best mobile IM apps around, and their desktop app is still one of the only IM clients that will sync all your info between devices. Now, they’ve now made their mobile and desktop even more tantalizing by making each of them free, with all the Pro features of the old versions in tow. That means that Trillian desktop users now have multiple location sign-in, themes, activity history, and other great features without subscribing.
Trillian’s also released version 5 for Windows, which includes a new interface that ditches the menu bar (Firefox-style), improves social networking integration, adds cloud-based chat history, and a new feature that lets you sync open IMs between all your devices.
