You got an email? from Twitter or UberMedia? I haven't received anything from either party except these tweets.
Edit: On second thought, I don't know what sort of personal communication standard I can hold UberMedia to. I don't think you actually need to register with them to use the client so they might not know who their users are to contact them. Well, apart from the 2.5 million twitter followers their account has.
I don't know the details on whether UberMedia asked for your email, but Twitter can email any Twitter account that has authorized UberTwitter regardless.
