We got our hands on a whole new app called iMovicha released through Cydia today which allows you to make free video/voice calls And IM to an iPhone, Android, Symbian, Windows , and Blackberry phone.

So why are all these features free?

iMovicha enables this through a 3G/Wifi connection. As long as you have an active internet connection you can IM or video/voice call your friends for free, even if they are not on an iPhone.
Some of its cool features include:

    * Video/Voice calling
    * IM
    * Presence group management
    * Contact management
    * Preference Management

For iPhone :

This app is available for free in Cydia via 'BigBoss' repo (you need to have a jailbroken iPhone).

For Android:

You can find this app for free via the app marketplace.
