However Twitter for Blackberry’s newest feature will help bring Twitter’s unofficial app into the 21st century.
[Y]ou can pinpoint your location in a neighborhood and include it your Tweets. […]

Unfortunately the latest update does not yet support video uploading (through third party services like TwitPic, Posterous or yFrog), although hopefully RIM will consider adding that feature when they roll out the next update.
