As has been many times said here, this application looks very promising (good layout, good functionality, except for missing facebook notifications) but is extremely slow and still has some stupid bugs like literally bombarding you with connection requests if you didn't set your phone to automatically connect to the internet.
I'm using the beta version of Java runtime from this page which made this app slightly more usable speed wise, but given that it seems to be a fairly late beta (0.7.462).
