More changes at Twitter. Yesterday a new version of Twitter for BlackBerry with changes including when you expand a Tweet to see the details view you can see images from pic.twitter.com in full resolution and RIM maps for geolocated Tweets. Twitter has also made it easier to see how a single Tweet fits into a broader conversation from the details view with previous Tweets and replies.

Today welcome changes to TweetDeck with new navigation features making it easier to browse and manage columns as well as a new menu icon on every Tweet gives users instant access to more Tweet actions such as like “Create link”,  and user-related actions, like “Block”.

Twitter says this makes it possible to report a user for spam, add an account to a list, delete your own Tweet, and much more, all without having to leave your main column view.
