I was just taking a look at the UberTwitter homepage as they have just put up a list of feature enhancements and bug fixes they are adding to the next beta release.  You will note that many of the items are already done.  Needless to say, UberTwitter beta 2 looks to be very promising.

UberTwitter is a new BlackBerry Twitter Client that went into public beta last Wednesday.  Once they get some of bugs such as battery drain worked out, it arguably may be the best BlackBerry Twitter Client out there.
