Trill (Nokia Symbian Twitter client)
Trill is a very usable Nokia Symbian client for Twitter. It has the right price (free, ;-)). Works with several columns (Home; Replies; Directs Messages; Favourites; Lists; Friends; and Trends), like desktop clients do. And, very important (I’m a Mac user), doesn’t need a previous reading of the manual for effective use on the go.
An (almost) perfect solution (it would be perfect if it could make the screen bigger, ;-)).
