I can't find it though. I only have 4 programs available to me: some feedback tool, something for the 9700, a traffic program, and one just called Blackberry Beta Zone.
It's not a big jump from v5.0.1.38, but I always like seeing what's new.
Once installed it requires a keycode. If you were a participated in the previous BBM beta program your old code works. If you do not have a code downloading right now is pointless because once you restart you wont be able to use your bbm.
I found out about this yesterday but got rid of my keycode when I thought the program was over. I e-mailed them to get a new code then found out it doesn't need one. Installed it and sure enough it didn't ask for a code. Received an email back today stating "At this time the BlackBerry Messenger Beta program does not support the Torch 9800". Funny, .39 is running great on my Torch.
The one feature I noticed that had been omitted on a few previous versions has been added back in. The ability to use BlackBerry contact pics instead of BBM pics. Really bothered me that they got rid of it and glad it's back.
