We use a lot of IMs in our daily life and to install and manage them all truly sucks.
This is where Trutap steps in. It is a global service for your mobile phone that will let you surf web, use IMs, social networking, blog, send SMS and much more. They have got all the IMs at one place.
Right now its in beta and more new features like sending SMS, inviting your friends, send emails etc are under testing. It supports almost all IMs like Yahoo, MSN, AIM, ICQ, Gtalk etc. You can also post comments and photos to your blog's on services like Typepad, Blogger and Photobucket and do social networking on Facebook and Flickr etc.
It is constantly adding more services and IM services. It supports a wide range of handsets except iPhone, probably because it is based on Java and it's audience prefers regular phones over smartphones.
But compared to other mobile applications and services, my vote goes for this. Sign up and give it a try, you will definitely find this app worth it.
