Just contacted HTC about the Twitter Peep problem. They responded with this.
Dear XXXXXXXXXX,
I understand the inquiry about the twitter application on the device. I would love to be able to provide a fix for the situation you are having. There is a hot fix made for the twitter application and it will be released with the next rom update for the device. I do not have a release date for the hot fix but I would advise to keep an eye on the pressroom at
www.htc.com/us for further information.

Sincerely,
Robert
