Palm WebOS Phones

I recently had to get my Palm Pre exchanged at the local sprint store they sent me a new one. before i upgraded my webos to the newsiest i checked it out to make sure everything was working properly i noticed that i could add yahoo messenger to my messaging section of my phone. It all had the yahoo branding and everything. But when i upgraded to the newest webos the option to add yahoo went away but the account i already set up for yahoo is still there. Soo i have a feeling yahoo support for at least messaging will be coming soon.....
