I get a message saying "unable to retweet". This existed on PR1.0, PR1.1 and now PR1.2. I have flashed the device multiple times (for different issues) but this one remained. Have removed and added account too. Update: Just a thought..I have my tweets set to private so only my contacts can see them. This is the only difference I can see between my account and others. Wonder if a privacy setting is causing this bug.
