By far this is one of the best mobile twitter aps available today. Its brought to us by Mobileways and its a very neat symbian aps which includes the usage of multiple twitter applications and images as well! A free download is available of Gravity Alpha v1.300.6300 for us to enjoy this application.
Tried to download it from vairous sites but mostly the certificate had expired and the installation never happened. Found this link with a working version and installation was a breeze!
Download it now and enjoy!
If that doesnt work i have it loaded below for you to enjoy
