It's rolling out. Personally, I think it's nothing but a UI upgrade and leaves performance upgrade behind.

Playing around with my Twitter clients and this is what I got. It seems that Echofon does not treat your own "reply" as a reply, tho UberTwitter does.

Can we assume that every-site about Twitter shall go down during any-launch of new features or upgrade?

I'm a fan of UberTwitter (UT), a small yet powerful Twitter client for
BlackBerry. To elevate the usage of UT, I frequently use shortcut keys
instead of the menu. Here are UT's shortcut keys:

U for update status / compose new tweet
R for reply to a status
J for reply all
L for ReTweet
D for direct message
G for go to user
S for search
O for refresh
V for favorite a status
Z for email a tweet

I didn't realize until now that UberTwitter is updating its application to 0.971. I really think that it's under the hood update, nothing to see outside. I'm still having fun with Twitter for BlackBerry, but it's good to have an update for UberTwitter.

I've been using it several days but this morning I realized that the title of New Tweet is already "What's happening?".
