ubertwitter + gtap

in ubertwitter options > advanced options
you are able to edit the twitter end point, in other words how ubertwitter access twitter. i'm in china, where twitter.com is blocked, so i've been searching for a proxy service to use with ubertwitter and i came across gtap
code.google.com/p/gtap/

could you guys have a mess around with the two and try to get ubertwitter working using the gtap addresses, because i've been trying for a while and can't seem to do it. even though it should be pretty simple.
