Mobile IM is the number four cellphone killer app  the other three are, in order, voice, SMS, and Snake  but, surprisingly, it’s the hardest to use. Of all the IM programs I’ve tried, only Danger has managed to make it seamless as possible. Mundu, a new product from Indian developers Geodesic is coming in a close second.
The product supports AIM, MSN Messenger, Yahoo Messenger, ICQ, Google Talk, and Jabber.
