I can't connect either. But then when I tried to go to Twitter on the web, I couldn't connect there either. It seems that the problem lies with Twitter.
Socialscope indicates to me that twitter is down due to a DoS attack. The backside API seems to have issue with everything, as many other twitter clients are effected too. Facebook reports a DoS attack too.
Still not working for now...damn
At first I thought it was just me having 2 twitter apps on my BB so I uninstalled UberTwitter, but Socialscope Lite still doesn't work.
