When I first signed up for Uber Twitter, I had issues as well. I didnt realize I had to sign up for mobile THEN install which ever program I wanted to use. Also keep in mind that when they ask for your username, they don't mean your email. They mean whatever name you use when posting tweets. I too use Uber Twitter. I like it much better than Twitterberry as there are more options to choose from. It runs smooth on my 8330 and I dont have as many freeze moments as I did with Twitterberry. Good Luck!
