The way this reads, or the way I read it he wants to convert flash videos on the titan to 3gp? As in having the titan convert flash videos to 3gp. I don't know if that would be wise as conversion is very cpu limited and could take a while on the 400mhz processor.
I do know of a good freeware app that can do it on your pc as it will convert almost any format to any other format given you have the time to do it or a beefy pc.
