All my other apps connect and I receive my email, so my data connection is fine. When I try to log in with Twitterberry, it keeps telling me that it could not connect and to try another method.
Are there any special settings needed for Twitterberry to work, or could my carrier be intentionally blocking it?
Did you also check permissions for the software? options>adv options> applications. Highlight the app then press menu>edit permissions. Make sure they are set to allow.
