Yahoo Go 2.0 Beta
 

Well I just checked and was able to download for the Mogul
Can't say I'm too impressed yet but there are some neat features.

I went to http://mobile.yahoo.com/go
Then clicked the Get Yahoo Go Now button.
From there select the Windows Mobile devices link.
Then select the Sprint PPC-6800 (even though it says coming soon on the picture).

After that I had it send me a text message and the download link was finally there. All it ever used to say is "Coming Soon".

Downloaded and installed. I'll have to play with it a little.

Yahoo! GO 2.0
 

I downloaded the module and the first thing I noticed is the keyboard issue when the screen is in landscape mode. This is the same issue as others have reported with the Windows Live search where regardless of the caps lock or the blue keys option, the keyboard puts in numbers and symbols.
I haven't played with the module enough to find any other issues.
EDIT forgot to mention I do have the new ROM (2.09) installed.
