I have wanted an IM application on my N95-3 for quite a while and I should have done my research before leaving for my visit to Asia (would have come in handy). Regardless, a little research on Google landed me to a product called "fring." fring is a VOIP and Chat program which enables you to log into a variety of existing IMs (Google Talk, AIM, ICQ, Yahoo, MSN, SKYPE etc). The most amazing thing is not only does it support VOIP on top of regular IM/Chat, it does it over WiFi and Data (3G or EDGE). This program is currently available for Symbian S60, Windows Mobile 5 & 6 and UIQ handsets.
Installing fring is simple. You can go to their website and fill out your phone number to receive an SMS text link or simply point a supported smartphone to their website where it will prompt for a download. I installed the 700+KB application to my phone's memory after installation. Its amazing how advance mobile applications have become; I love the fact that most applications can be installed stand-alone over the handset today. This application does require you to register an account name and password over the handset; with four required fields filled out and submited, I was on my way to connect to my IM of choice.
So far, I've only signed into Google Talk and used it at its bare minimum (instant message). I've yet to test its VOIP function via Data network or WiFi. The operation thus far has been flawless and simple to use. I am thrilled to see that most of the popular IM applications are supported in a one stop shop. Stayed tuned for more updates once I get a chance to test its VOIP using Google Talk and Skype.
