I have blackberry curve 8900. whenever i tried to log in to ubersocial it always says "error validating credentials". i was able to log in before but not now anymore. my password and username are correct. i can even log in to twitter for blackberry but i prefer ubersocial.
i can already reboot my phone by pulling out the battery. i make sure that my all permissions are set to allow and my mobile network is set to "ON". but still nothing happened. by the way i'm using wifi as of now not BIS and i mark "use wifi if available" check

For the connection settings do you have it set to auto or something else (aside from the wifi option). I remember that used to prevent some people from logging in.

If problem persists, try sending Uber an email. I've found them to be quite responsive in the past.
