Integrating the most popular IM clients into a single desktop application, Heysan is a brand new mobile site that lets you chat with your friends on MSN, AIM, ICQ, Yahoo and GTalk through your mobile and that too for free. Of course telco data services apply, but the patent pending technology claims to work with any service provider and any phone model in any part of the world. Optimized for mobile browsing, the service allows messages to be pushed via SMS to your phone if you’re online, which is exactly what Yahoo and MSN are already offering as a paid service on various networks, but since Heysan is letting you IM for free, it might just be worth your while to give it a go!
