Blank screen on Twitter app

All of a sudden Twitter has stopped working on my phone. Whenever I click on the app twitter loads to blank white screen with a blue bar acoss the top. Also when I try to go into the twitter settings menu it freezes and I have to go back to the home screen and end the settngs process before I can use it again.

I've tried deleting and re-installing the app, turning phone on and off, resetting the network settings and restoring from a back up and nothing works. I also tried downloading Echofon, another twitter app which wouldn't work either which suggests the problem is with the phone.
