Update: The Beta Zone has removed the download link for Twitter for BlackBerry v126.96.36.199, which technically wasn't even suppose to be released last night, because a lot of users were having issues sending tweets (the most basic function). If you're having this issue, you can downgrade to v188.8.131.52 (which I recommend) or v184.108.40.206. If you're not being affected by this, no need to downgrade, obviously.
Twitter for BlackBerry v220.127.116.11 was just released 6 days ago, but unfortunately it was terrible. Apparently, in order to fix the timeline issue (which was fixed in .7), they had to redo the code completely which ended up screwing up a few other things in the process.
Thus, now 18.104.22.168 is out and it is a lot better. The change log hasn't been updated yet from .7 since it was sent out late last night/early this morning as well.
