Twitter for BlackBerry has now moved beyond the BlackBerry Beta Zone Gold Release and v3.1.0.20 has been released into BlackBerry App World. Some of the changes and fixes do carry over from the previous version as noted below:

• Updated Twitter Bird
• Undo Retweet
• New tweet details screen
• Sharing Tweets over email fails to keep links shortened
• Reply Hotkey not working and menu item missing on the Tweet Details screen if the Tweet is Retweeted by you
• When replying to a Tweet with a location, location call out pops up over top of the text in the Tweet
• Main account was deleted/logged out from app after experiencing network issues
• Spell check dialog appears as well as the suggested usernames in Sign Up screen

You can grab it now from BlackBerry App World or direct from the BlackBerry mobile site. If you’re not seeing it as of yet, refresh app world or just wait a little bit longer as it’s still filtering through the system. If you cant see it try using alt+rst to reset your app world cache.
