Looks like they have added some of the missing desktop features to the new Yahoo Messenger for the Blackberry. From a quick look, here's what is new.

-- Shows a persons avatar (if they have one)
-- You can now communicate with Windows Live Messenger contacts (seemed a little slow in sending messages, but it works)
-- You can control who sees you online directly from Yahoo Messenger in the Blackberry.
-- Couple new emoticons

Just saw it also does file sending as well, trying it out now.

oh no! It doesn't work on AT&T!

wow. this is actually really nice.

Yes, I just upgraded and now it no longer works for me either. Oh well my GT does and my Jivetalk does.

how do you make it work with Windows contacts?

So, a little more trouble than what I wanted. But YM wouldnt work after loading, although it showed in the application list as installed. I could not find any icon to start up the program and kept getting 'Uncaught exception java.lang.error' after each restart. I wiped the device, once reloaded and back up, I downloaded YM again and works fine now. Not sure why it wouldnt work in the first place?

Another new feature is a setting in options to show conversations in message list.

to clarify, i have version 2.33 and still can only add Yahoo contacts and cannot see the Windows contacts that I can see from my desktop version.

Now, we just need a BlackBerry with all of the existing service books to download/install this, add the service book to the device, and make us a nice little .ipd file with all o' the books. :D Any takers?

desktop windows lives users can see us yahoo contacts online if we're added to their list, but wecant see them online on our bb's. however, i can send a msn contact an offline msg and they'll get it, but i wont always know when theyre online and when theyre not

G4rr3tt ... think you'd be up for gettin' us that service book, ol' buddy ol' pal?

If you can see them on the desktop, you should be able to see them on the BB. I am able to see mine.

I'd also love to see some service books for this one. I wonder why it changed for this but not GTalk?

I'm able to see my windows live contacts in BB yahoo messenger BUT and that is strange for me, I can't see what they are typing to me, I just see "Contact name is typing..." I think is a bug, can anyone confirm this?
I make a precision, yahoo contacts can write to me and it's works without problems.

That is exactly the problem that I have now after installing YM2. Don't really want to wipe everything, but it worked for you, and I did a backup last night, so I guess it's worth a shot.

it looks like i have the same service book as i did for the old Y!M ( BBFS2 [YHO] ) ....
i checked and nothing looks different, however i cant tell when any msn contacts are online...kinda lame

Anyone on AT&T have this working?

I cant believe it isnt working on AT&T. Any idea why or how to make it work? Who to contact?

I am sure Tech support wont do anything since they dont have to service it!

Today I am seeing same problem. When I log out and log back in I get an offline message from them. Had no trouble yesterday, today is another story.

Any one have the older verison? I want to uninstall and try to put back the old one.

co-sign, i need help for my bb8820 please

This happens for me. I can see MSN contacts and they can see me. They get my messages ok but i do not get theirs unless i logout and log back in again.
