Twitter Authentication Error

[if_then_else]

Hello, I'm having a problem with the twitter apps of my Samsung i5700, I've looked all over the web and I can't seem to find a solution. I'm hoping you have some idea of what the problem is and how to solve it:

Everytime I try to log in into my twitter account, some kind of authentication error occurs, I've tried several Twitter clients (Android stock, Twydroid, Twitcaster...), and it's always the same error. I've deleted cache, made a factory reset, and even reinstall Android all over again, but the problem persists. I've tried on Android 1.5 and Samdroid 2.1, and it's always the same deal. I've managed to get a log of several log in tries with the andoid stock app for Twitter, and here it is:

You can see several "Authentication error: Unable to respond to any of these challenges: {..." on the log, corresponding to my log in tries.

Anyone has any idea what the problem could be? I'd really apreciate your help.

Tell me if you need more information.


Thanks beforehand!
