Nimbuzz recently launched a beta version of their service. It provides free instant messaging as well as a very cool VOIP service for your mobile phone (like what Skype provides for your PC). Best of all (at least from my perspective), their IM back-end is powered by Wildfire. Nimbuzz is a great example of how communications are converging in innovative ways. As we're seeing with a number of customers, Wildfire is in the thick of that process.
My lame U.S. phone doesn't have J2ME support so I haven't been able to actually try the service yet. I'll have to hunt down somebody in the office with the required equipment...

They should have used Jingle

We seriously considered that, Sander. A big disadvantage for Jingle is that it's still in development. Choosing for Jingle, despite all the advantages it offers, is still somewhat risky. SIP on the other hand has already proven to be a workable solution. That said, we do make use of (lib)jingle to connect to Google Talk (that software hasn't been plugged into our live server yet though).
