Sorry for not getting back to you sooner. I have an 8310, which doesn't have WIFI as an option... =( Anyway, using my normal data connection, I have no trouble with Google apps running, get my Gmail updates, GoogleMaps, etc. For IM, I'm using BeeJive which is an 'all-in-one' type of client. Mind you, BBM is on a sealed network, so you can only access it with BIS or BES. I use Jmirc for IRC....Haven't sourced Yahoo apps yet, though. I don't know which (if any) of these apps will work via WIFI, but you can always try. Trying to track down apps that will do what you want, is nothing more than making close, personal friends with your favorite search engine.
