Meebo App
Works pretty well as far as mobile IM clients go. They run stuff through their servers so sometimes it's a little slow to sync up messages you've received in the background (and I'd be especially cautious about sensitive conversations), but you get push notifications w/out sucking down battery life *cough*skype*cough*. Supports all of the IM networks that I use and then some. Oh yeah, and it's free.
