Just a quick update. It seems that there is only one dock mode & when I don't have the external speakers connected to my desktop dock, the phone goes into clock mode, so I've been doing that. As for Twitter contacts, still haven't found a way to add them to my contacts.
That said, I LOVE this phone. I get much better battery life on this with the standard battery then I did on my Rezound with the extended battery. I like that you can set different text message alerts for contacts with the stock Text Messenger device.
