So I mainly use google talk as my primary IM client on my computer and my Palm Pre but I have some friends who also use Yahoo for their IM’ing needs (including Allison) so I have been interested in getting that ability on my Pre.

Well today I discovered a messaging plugin that allows you to connect to more service then the default ones.  It adds functionality for Yahoo, ICQ, Jabber, Office Communicator, ect.

Now I have not tried them all as I dont really use any of the other services but I can say that the Yahoo one does work.  I was able to login, see my friends online and have a chat with one.  So there ya go some more added features to your Pre

Note : There has been some talk that Yahoo will be included by Palm in the future as a default option so if you are not kool with installing packages and stuff you may still see that as an option soon.
